In this article, we will explain what spinal stenosis is, the causes, symptoms, diagnosis, and treatment of spinal stenosis in detail, and provide some tips on how to prevent or manage this condition.
What is Spinal Stenosis?
Spinal stenosis is a condition that occurs when the space within the spine becomes narrow and puts pressure on the spinal cord and/or nerve roots. This can cause pain, numbness, tingling, weakness, and other problems in different parts of the body, depending on the location and severity of the stenosis. Spinal stenosis can affect any part of the spine, but it is more common in the lower back (lumbar spine) and the neck (cervical spine).
Spinal stenosis is usually caused by age-related changes in the spine, such as arthritis, bone spurs, thickened ligaments, or herniated disks. However, some people may be born with a congenital spinal stenosis, or develop it due to other factors, such as tumors, injuries, infections, or diseases that affect the spine.
Spinal stenosis can be diagnosed by a physical examination and imaging tests, such as X-rays, MRI, CT scan, or myelogram. The treatment options depend on the type, location, and severity of the stenosis, as well as the patient's overall health and preferences. The treatment may include medications, physical therapy, steroid injections, or surgery.
What Causes Spinal Stenosis?
The most common cause of spinal stenosis is the wear-and-tear damage to the spine that occurs over time, especially in older adults. This can lead to various changes in the spine that reduce the space available for the spinal cord and nerve roots. These changes include: bone spurs, herniated disks, thickened ligaments, tumors, spinal injuries.
Bone spurs: These are bony growths that form on the edges of the spinal bones (vertebrae) due to arthritis or other degenerative conditions. Bone spurs can protrude into the spinal canal or the openings where the nerve roots exit the spine (foramina), and compress them.
Herniated disks: These are the soft cushions that act as shock absorbers between the vertebrae. Sometimes, the outer layer of a disk can tear and allow some of the inner material to leak out. This can press on the spinal cord or nerve roots, or cause inflammation and irritation.
Thickened ligaments: These are the tough bands of tissue that connect the vertebrae and help stabilize the spine. Over time, they can become stiff and thick due to aging or inflammation. This can cause them to bulge into the spinal canal or foramina, and narrow them.
Tumors: These are abnormal growths of tissue that can develop inside or outside the spine. They can be benign (noncancerous) or malignant (cancerous). Tumors can invade the spinal canal or foramina, or compress them by pushing on the surrounding structures.
Spinal injuries: These are the traumas or accidents that can damage the spine, such as falls, car crashes, sports injuries, or violence. Spinal injuries can cause fractures, dislocations, or instability of the vertebrae, which can reduce the space within the spine. They can also cause swelling or bleeding of the nearby tissues, which can put pressure on the spinal cord or nerve roots.
Some people may have a congenital spinal stenosis, which means they are born with a narrow spinal canal or foramina. This can be due to a genetic disorder, such as achondroplasia (a type of dwarfism), or a developmental abnormality of the spine. Congenital spinal stenosis can become symptomatic later in life, especially if the spine undergoes further degeneration or injury.
Other factors that can cause or contribute to spinal stenosis include:
- Paget's disease
Infections: These are the diseases caused by bacteria, viruses, fungi, or parasites that can affect the spine. Infections can cause inflammation, abscesses, or bone destruction, which can reduce the space within the spine or compress the spinal cord or nerve roots.
Paget's disease: This is a disorder that affects the bone metabolism and causes abnormal bone growth and remodeling. Paget's disease can affect any bone in the body, including the spine. It can cause the vertebrae to become enlarged, deformed, or weak, which can reduce the space within the spine or compress the spinal cord or nerve roots.
Scoliosis: This is a condition that causes the spine to curve sideways, forming an S-shape or a C-shape. Scoliosis can affect any part of the spine, but it is more common in the thoracic spine (upper back) or the lumbar spine (lower back). Scoliosis can cause the spinal canal or foramina to become narrow, and compress the spinal cord or nerve roots.
Spinal Stenosis Symptoms
Spinal stenosis can cause different symptoms depending on the location and severity of the stenosis, as well as the affected nerves. Spinal stenosis symptoms can vary from mild to severe, and can be intermittent or constant. The symptoms can also get worse over time, or be triggered by certain activities or positions.
The most common symptoms of spinal stenosis include:
- Balance problems
- Bowel or bladder problems
Pain: This is the sensation of discomfort, soreness, or aching that can occur in the back, neck, arms, legs, or buttocks. The pain can be dull, sharp, burning, or throbbing, and can range from mild to severe. The pain can be localized to the area of the stenosis, or radiate to other parts of the body along the affected nerve. The pain can be worse when standing, walking, or bending backward, and better when sitting, lying down, or bending forward.
Numbness: This is the loss of sensation or feeling in the skin or muscles. Numbness can occur in the back, neck, arms, legs, or buttocks, depending on the affected nerve. Numbness can affect the ability to feel touch, temperature, or pain, and can increase the risk of injury or infection.
Tingling: This is the sensation of pins and needles, prickling, or crawling that can occur in the skin or muscles. Tingling can occur in the back, neck, arms, legs, or buttocks, depending on the affected nerve. Tingling can be uncomfortable or annoying, and can indicate nerve damage or irritation.
Weakness: This is the loss of strength or power in the muscles. Weakness can occur in the back, neck, arms, legs, or buttocks, depending on the affected nerve. Weakness can affect the ability to perform daily activities, such as walking, lifting, or holding objects, and can increase the risk of falls or injuries.
Balance problems: These are the difficulties with maintaining stability or coordination. Balance problems can occur due to spinal stenosis in the cervical spine, which can affect the signals from the brain to the rest of the body. Balance problems can cause dizziness, vertigo, or unsteadiness, and can increase the risk of falls or injuries.
Bowel or bladder problems: These are the difficulties with controlling the functions of the urinary or digestive systems. Bowel or bladder problems can occur due to spinal stenosis in the lumbar spine, which can affect the nerves that control these organs. Bowel or bladder problems can cause incontinence (loss of control), retention (inability to empty), or urgency (need to go frequently), and can affect the quality of life and hygiene.
Some people with spinal stenosis may have no symptoms, or only mild symptoms that do not interfere with their daily activities. However, some people may have severe symptoms that affect their mobility, function, and well-being. In rare cases, spinal stenosis can cause a serious condition called cauda equina syndrome, which occurs when the nerve roots at the lower end of the spinal cord are compressed. This can cause severe pain, numbness, weakness, and paralysis in the lower body, as well as loss of bowel or bladder control.
Cauda equina syndrome is a medical emergency that requires immediate treatment to prevent permanent damage.
To diagnose spinal stenosis, the doctor will first ask the patient about their medical history and symptoms, such as when they started, how often they occur, and what makes them better or worse. The doctor will also perform a physical exam, which may include checking the patient's posture, spine alignment, range of motion, reflexes, sensation, and muscle strength. The doctor may also ask the patient to walk, stand, sit, or bend in different positions to see how their symptoms change.
To confirm the diagnosis and determine the exact location, cause, and severity of the spinal stenosis, the doctor may order one or more imaging tests, such as:
- X-rays: These are the images of the bones that can show the shape, size, and alignment of the vertebrae, as well as any bone spurs, fractures, or deformities that may be causing the stenosis. X-rays can also show the narrowing of the spinal canal or the foramina, which are the openings where the nerve roots exit the spine.
- MRI: This is a scan that uses a strong magnet and radio waves to produce detailed images of the soft tissues, such as the spinal cord, nerve roots, disks, and ligaments. MRI can show the extent of the stenosis, as well as any inflammation, compression, or damage to the nerves. MRI can also show the blood flow and oxygen level in the spine, which can indicate the health and function of the spinal cord.
- CT scan: This is a scan that uses X-rays and a computer to create cross-sectional images of the body. CT scan can show the bone structure and any abnormalities that may be causing the stenosis. Sometimes, a contrast dye is injected into the spinal canal to outline the spinal cord and nerves. This is called a CT myelogram, and it can show herniated disks, bone spurs, and tumors.
- Electromyography (EMG): This is a test that measures the electrical activity of the muscles and nerves. EMG can help evaluate the function and damage of the nerve roots that are affected by the stenosis. EMG can also help rule out other conditions that can cause similar symptoms, such as peripheral neuropathy or radiculopathy.
The doctor may also order some blood tests to check for any infections, inflammation, or diseases that can affect the spine, such as rheumatoid arthritis, ankylosing spondylitis, or diabetes.
Spinal Stenosis Treatment
The treatment of spinal stenosis depends on the severity of the symptoms, the location and cause of the stenosis, and the patient's overall health and preferences. Spinal stenosis treatment options may include:
- Physical therapy
- Steroid injections
- Needle procedure for thickened ligaments
Medications: These are the drugs that can help relieve pain, inflammation, or nerve irritation caused by spinal stenosis. Some of the common medications used for spinal stenosis are nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, which can reduce swelling and pain; antidepressants, such as doxepin or clomipramine, which can help ease chronic pain; anti-seizure drugs, such as gabapentin or pregabalin, which can reduce pain caused by nerve damage; and opioids, such as oxycodone or hydrocodone, which can provide short-term pain relief. However, medications may have side effects, such as stomach ulcers, liver damage, addiction, or drowsiness, and should be used with caution and under the doctor's supervision.
Physical therapy: This is the use of exercises, stretches, massage, heat, cold, or electrical stimulation to improve the strength, flexibility, and stability of the spine, and to reduce pain and inflammation. Physical therapy can also help improve the balance, coordination, and gait of the patient, and prevent further injury or disability. A physical therapist can design a customized program for each patient, depending on their condition and goals.
Steroid injections: These are the injections of corticosteroid drugs, such as betamethasone, into the space around the pinched nerve, to reduce inflammation and pain. Steroid injections can provide temporary relief for some patients, but they may not be effective for everyone, and they may have side effects, such as infection, bleeding, nerve damage, or bone weakening. Therefore, steroid injections should be used sparingly and only when other treatments have failed.
Needle procedure for thickened ligaments: This is a minimally invasive procedure that uses needle-like tools inserted through the skin to remove some of the thickened ligament that is narrowing the spinal canal or foramina. This procedure can create more space for the nerve roots and relieve some of the symptoms. However, this procedure may not be suitable for everyone, and it may have risks, such as infection, bleeding, nerve damage, or spinal instability.
Surgery: This is the use of an operation to create more space for the spinal cord or nerve roots, and to remove or repair the structures that are causing the stenosis, such as bone spurs, herniated disks, tumors, or thickened ligaments. Surgery can provide long-term relief for some patients, but it may not be necessary or effective for everyone, and it may have complications, such as infection, bleeding, nerve damage, or spinal instability. Therefore, surgery should be considered as a last resort, and only when the symptoms are severe, disabling, or progressive, and when other treatments have failed.
Some of the common surgical procedures for spinal stenosis are:
- Laminectomy: This is the removal of part or all of the lamina, which is the back part of the vertebra that covers the spinal canal. This procedure can create more space for the spinal cord and nerve roots, and relieve the pressure and pain. Laminectomy can be done for any part of the spine, but it is more common for the lumbar spine (lower back) or the cervical spine (neck).
- Foraminotomy: This is the enlargement of the foramen, which is the opening where the nerve root exits the spine. This procedure can create more space for the nerve root and relieve the compression and pain. Foraminotomy can be done for any part of the spine, but it is more common for the cervical spine (neck) or the thoracic spine (upper back).
- Spinal fusion: This is the joining of two or more vertebrae together with bone grafts or metal implants, to stabilize the spine and prevent abnormal motion. This procedure can help reduce pain and improve function, but it can also limit the flexibility and mobility of the spine. Spinal fusion can be done for any part of the spine, but it is more common for the lumbar spine (lower back) or the cervical spine (neck).
The choice of the surgical procedure depends on the type, location, and cause of the stenosis, as well as the patient's overall health and preferences. The doctor will discuss the benefits and risks of each procedure with the patient, and help them make an informed decision. The recovery time and outcome of the surgery may vary depending on the individual case, but generally, most patients can resume their normal activities within a few weeks or months after the surgery.
Prevention and Management of Spinal Stenosis
Although spinal stenosis is often related to aging and wear and tear, there are some steps that people can take to prevent or delay its onset, or to manage its symptoms. Some of the prevention and management strategies include:
- Maintaining a healthy weight: Excess weight can put more stress and pressure on the spine, and contribute to the degeneration of the disks and joints. Keeping a moderate weight can help reduce the load on the spine and prevent further damage.
- Quitting smoking: Smoking can impair the blood flow to the spine, and affect the health and function of the disks and bones. Smoking can also increase the risk of inflammation, infection, and osteoporosis, which can worsen the spinal stenosis. Quitting smoking can help improve the blood circulation and oxygen delivery to the spine, and prevent further deterioration.
- Practicing good posture: Poor posture can cause the spine to curve or bend abnormally, and reduce the space within the spinal canal or foramina. Poor posture can also strain the muscles and ligaments that support the spine, and cause pain and stiffness. Practicing good posture can help maintain the natural alignment and curvature of the spine, and prevent or relieve the compression of the spinal cord or nerve roots. Good posture involves keeping the head, shoulders, and hips in a straight line, and avoiding slouching, hunching, or twisting the spine.
- Eating a balanced diet: Eating a balanced diet rich in nutritious foods can benefit the spine health. A balanced diet can provide the essential nutrients, such as calcium, vitamin D, magnesium, and phosphorus, that are needed for the growth and maintenance of the bones and disks. A balanced diet can also help prevent or manage conditions that can affect the spine, such as osteoporosis, arthritis, or diabetes.
- Exercising regularly: Exercising regularly can help strengthen the muscles and ligaments that support the spine, and improve the flexibility and stability of the spine. Exercising can also help improve the blood flow and oxygen delivery to the spine, and promote the healing and repair of the damaged tissues. Exercising can also help reduce pain, inflammation, and stiffness, and improve the mood and quality of life. Some of the best exercises for spinal stenosis are low-impact aerobic exercises, such as walking, swimming, or cycling, and stretching exercises, such as yoga or pilates.
- Using assistive devices: Using assistive devices, such as back braces for spinal stenosis, splints, or canes, can help support the spine and reduce the pressure on the spinal cord or nerve roots. Assistive devices can also help improve the balance, coordination, and gait of the patient, and prevent falls or injuries. A doctor or a physical therapist can recommend the appropriate type and size of the assistive device for each patient, and teach them how to use it properly.
- Managing stress: Stress can have a negative impact on the spine health, as it can cause the muscles and ligaments to tense up, and increase the pain and inflammation. Stress can also affect the mood and well-being of the patient, and interfere with their daily activities and sleep quality. Managing stress can help relax the muscles and ligaments, and reduce the pain and inflammation. Managing stress can also help improve the mood and well-being of the patient, and enhance their coping skills and resilience. Some of the ways to manage stress are meditation, breathing exercises, massage, acupuncture, or counseling.
Spinal stenosis can significantly impact an individual's quality of life, causing discomfort, restricted mobility, and in severe cases, debilitating pain. However, with the right approach to management and treatment, individuals can find relief and regain functionality. One such solution is the use of a back brace, such as the Back Brace for Lower Back Pain from Zofore Sport.

What is the best thing to do for spinal stenosis?
The best thing to do for spinal stenosis depends on the severity of your symptoms and the location of the narrowing. Some common treatment options include medications, physical therapy, steroid injections, and surgery. You should consult with your doctor to find the most suitable treatment plan for your condition.
What are the final stages of spinal stenosis?
The final stages of spinal stenosis are marked by severe pain, loss of sensation, and loss of function in the affected areas of the body. The spinal canal becomes so narrow that it compresses the nerves and the spinal cord, leading to nerve damage and paralysis. This is a serious condition that requires urgent medical attention and surgery.
Can you fix spinal stenosis without surgery?
Yes, you can fix spinal stenosis without surgery in some cases. Non-surgical treatments for spinal stenosis include self-care, physical therapy, medications, steroid injections, chiropractic care, and alternative therapies. However, surgery may be necessary if your symptoms are severe or do not improve with conservative measures.
What is the best sleeping position for spinal stenosis?
There is no definitive answer to this question as different people will have different preferences. Some people with spinal stenosis may find that sleeping on their back with a pillow under their knees is the most comfortable position, while others may prefer sleeping on their side with a pillow between their knees. You could also try sleeping in a semi-reclined position with pillows or a recliner chair that keeps your head and knees elevated.
What foods should I avoid with spinal stenosis?
Some foods that you should avoid with spinal stenosis are those that can increase inflammation, such as red meat, caffeine, and alcohol. These foods can worsen your pain and stiffness. You should also limit your intake of omega-6 fatty acids, which are found in vegetable oils, processed foods, and some nuts and seeds. Omega-6 fatty acids can promote inflammation when consumed in excess.
