17499 Spinal Stenosis

Overview

Spinal stenosis is a condition in which the spaces inside the spine become narrower than normal. This narrowing can put pressure on the nerves that travel through the spine, which may cause pain, numbness, tingling, or weakness in the back, neck, arms, or legs.

Yes, spinal stenosis becomes more common as people get older. It is one of the most common reasons for back and leg pain in adults over 50.

Spinal stenosis mostly affects older adults, typically people over 50. It can also affect younger people who are born with a narrow spinal canal or who have spinal injuries.

Symptoms

Common symptoms

• Dull ache or stiffness in the back or neck
• Numbness, tingling, or burning feeling in the hands, arms, legs, or feet
• Weakness in a leg or arm
• Cramping or heaviness in the legs after walking or standing
• Pain that eases when you sit or lean forward
• Problems with balance or coordination

Symptoms in children

• Spinal stenosis is rare in children, but when it occurs, it is usually due to a condition present at birth.
• Symptoms in children may include leg pain, unusual tiredness when active, changes in walking pattern, or loss of bladder or bowel control in severe cases.

Symptoms in older adults

• Difficulty walking long distances because of leg pain or heaviness
• Stooped posture when walking or standing
• Radiating pain from the lower back down the legs (similar to sciatica)
• Weakened legs or a feeling that the legs give way
• Less common symptoms include falls and loss of balance

Causes

Main causes

• Age-related wear and tear on the spine, including osteoarthritis
• Bone spurs that grow into the spinal canal
• Herniated discs (the cushions between spinal bones bulge out)
• Thickened ligaments that press on nerves
• Spinal injuries or fractures
• Congenital (present at birth) narrowing of the spinal canal
• Tumors, although rare

Risk factors

• Age over 50
• Arthritis or osteoarthritis
• Previous spinal injury or surgery
• Repetitive heavy lifting or activities that strain the spine
• Being overweight or having obesity
• A family history of spinal problems

When to see a doctor

See a doctor urgently if:

• New or worsening weakness in your arms or legs
• Loss of balance that makes you fall
• Difficulty passing urine or stool
• Back pain with fever, chills, or unexplained weight loss

Book a routine appointment if:

• Back, leg, arm, or neck pain that lasts more than a few weeks
• Numbness or tingling that does not go away
• Pain that interferes with daily activities, work, or sleep
• You have questions or concerns about your spine or symptoms

Diagnosis

Your doctor will start by asking about your symptoms, medical history, and daily activities. They will examine your spine, check your muscle strength, reflexes, and sensation, and may ask you to walk, bend, or lean in certain ways to see which positions ease or worsen your symptoms.

Tests that may be done

• X-rays — to look at the bones in your spine
• MRI (magnetic resonance imaging) — gives detailed pictures of the spine, nerves, and soft tissues
• CT scan (computed tomography) — helps show narrow spaces and bone details
• Nerve conduction studies or electromyography (EMG) — to check how well nerves are working

What to expect at your appointment

Diagnosis usually happens in a primary care clinic or a specialist’s office. If your doctor suspects spinal stenosis, they may refer you to a specialist such as a neurologist, orthopaedic surgeon, or pain specialist. The process may take a few visits, but you will not need invasive tests unless there is a clear reason.

Treatment

Treatment for spinal stenosis focuses on relieving pain and improving mobility. Most people do not need surgery. Your doctor will recommend a plan based on your symptoms, age, overall health, and how much the condition affects your daily life.

Self-care at home

• Stay as active as you safely can — rest too much can make muscles weaker
• Try gentle exercises like walking, swimming, or cycling
• Use heat packs or cold packs on painful areas
• Avoid heavy lifting and twisting movements
• Choose furniture and chairs that support your back
• Use a walking frame or stick if it helps you feel steady

Medical treatments

Your doctor may recommend physical therapy to strengthen the muscles that support your spine, gentle stretching to improve flexibility, and pain management strategies. Some people benefit from medicines that reduce pain or inflammation, but it is important to take any medicine as suggested by a healthcare professional. Others may have steroid injections around the spine to temporarily reduce swelling and pain. Always discuss the benefits and risks with your doctor.

When is surgery considered?

Surgery is considered when symptoms are severe, when there is progressive nerve damage, when walking becomes very difficult, or when bowel or bladder function is affected. Surgery aims to widen the spinal canal and relieve pressure on nerves. Your specialist will explain the options and what to expect.

Living with this condition

Living with spinal stenosis means learning to pace yourself. Break up long walks into shorter ones, rest when you need to, and avoid positions that make pain worse. Lean forward slightly or sit down to ease pressure on your lower back. Plan your day around activities that are more comfortable for you.

Lifestyle tips

• Maintain a healthy weight to reduce load on your spine
• Keep your core and back muscles strong with regular exercise
• Use proper posture and body mechanics for lifting or bending
• Wear comfortable, low-heeled shoes with good support
• Quit smoking — smoking can affect blood flow and speed up spine degeneration

Diet and exercise

A balanced diet with plenty of vegetables, fruits, whole grains, and lean protein helps keep you healthy and manage your weight. Low-impact exercise like walking, swimming, water aerobics, and stationary cycling are usually well-tolerated. A physiotherapist can design a safe exercise routine tailored to you. Stretch gently and avoid high-impact sports that jar the spine.

Mental health and emotional wellbeing

Living with chronic pain can feel exhausting and frustrating. It is normal to feel anxious, low, or overwhelmed at times. Remember that your feelings are valid. Talking to friends, family, or a counsellor can help. Many people learn to manage their condition well, and treatment often improves quality of life.

Prevention

It is not always possible to prevent spinal stenosis because aging and genetics play a role. However, you can help slow its progress and reduce symptoms by staying active, keeping a healthy weight, using safe lifting techniques, and taking care of your spine.

Complications

If left untreated

• Progressive weakness in the legs or arms that may become permanent
• Loss of sensation or reflex changes
• Difficulty walking or standing for long periods
• Rare but serious: cauda equina syndrome, which affects bladder and bowel function and requires urgent surgery

Long-term outlook

For most people, spinal stenosis does not cause severe disability. With proper treatment, many experience meaningful relief and can stay active. Even when symptoms continue, they often remain stable for years. Surgery helps many people when other treatments do not. There is every reason to feel hopeful about managing this condition.
