Sciatica living in older adults

Overview

Sciatica is pain that travels along the sciatic nerve, which runs from your lower back, through your buttock, and down your leg. It usually affects only one side of the body. Sciatica is not a condition itself, but a symptom of another problem in the lower back, such as a slipped disc or narrowing of the spine.

Yes, sciatica is very common. Many adults, especially those over 50, will experience it at some point in their life.

Sciatica can happen to anyone, but it is more common in people over 50, those who are overweight, and people whose jobs involve lifting or sitting for long periods.

Symptoms

Common symptoms

• Pain that starts in the lower back and spreads down one leg, sometimes into the foot
• Numbness or a pins-and-needles feeling in the leg or foot
• Weakness in the leg or foot

Symptoms in children

• Children can get sciatica, but it is rare. Symptoms may include leg pain, limping, or refusing to walk. If your child has these symptoms, see a doctor.

Symptoms in older adults

• Pain may be less sharp and more like a deep ache or burning
• Pain may get worse when standing or walking and improve when sitting (common with spinal stenosis)
• You may have trouble balancing or feel like your leg is giving way

Causes

Main causes

• Herniated disc (a bulging disc in the spine presses on the nerve)
• Spinal stenosis (narrowing of the spaces in the spine that pinches the nerve)
• Spondylolisthesis (one vertebra slips forward over the one below)
• Rarely, an infection or tumor pressing on the nerve

Risk factors

• Age – most common in people over 50
• Being overweight or obese
• Jobs that require heavy lifting, twisting, or long periods of sitting
• Diabetes, which can damage nerves
• Smoking – it reduces blood flow to the spine

When to see a doctor

See a doctor urgently if:

• If you have any emergency symptoms (loss of bladder/bowel control, numbness in groin, sudden leg weakness), call your local emergency number immediately.
• If you have sudden severe pain or weakness that makes it hard to walk, see a doctor the same day.

Book a routine appointment if:

• If your symptoms last longer than 4 to 6 weeks without improvement
• If the pain becomes worse over time
• If you have trouble doing daily activities or sleeping because of the pain

Diagnosis

Your doctor will ask about your symptoms and do a physical exam. They will check your strength, reflexes, and sensation in your legs. They may also ask you to walk and do simple movements.

Tests that may be done

• Usually no tests are needed. If symptoms persist or are severe, your doctor may order an MRI scan (a special picture of your spine) to look for nerve compression.

What to expect at your appointment

The doctor may perform a straight leg raise test (lifting your leg while you lie on your back) to see if it causes pain. This helps confirm sciatica.

Treatment

Treatment focuses on relieving pain and helping you return to your normal activities. Most people recover with simple self-care and do not need strong medicines or procedures.

Self-care at home

• Stay active – gentle walking and stretching are better than bed rest
• Apply heat or cold packs to the painful area for 15-20 minutes several times a day
• Use over-the-counter pain relievers such as paracetamol or anti-inflammatory medicines (ask your doctor or pharmacist which is safe for you)
• Try gentle yoga or physical therapy exercises to strengthen your back and core

Medical treatments

If self-care is not enough, your doctor may recommend physical therapy, prescription pain medicines, nerve pain medications, or epidural steroid injections (a shot of medicine near the nerve to reduce swelling). These treatments help manage pain while your body heals.

When is surgery considered?

Surgery is rarely needed. Doctors only consider it if you have severe weakness, loss of bowel/bladder control, or if other treatments have not helped after several months. The most common surgery is a microdiscectomy to remove part of a herniated disc.

Living with this condition

Sciatica can be frustrating, but most people get better. Listen to your body and avoid activities that make the pain worse, such as heavy lifting or sitting for hours. Alternate sitting, standing, and walking throughout the day.

Lifestyle tips

• Maintain a healthy weight to reduce pressure on your back
• Practice good posture when sitting, standing, and sleeping (use a lumbar support if needed)
• When lifting objects, bend your knees and keep your back straight – never twist while lifting

Diet and exercise

A balanced diet with plenty of fruits, vegetables, and whole grains can help reduce inflammation. Gentle exercises like swimming, walking, or using a stationary bike are good for keeping your back flexible and strong. A physical therapist can show you safe moves.

Mental health and emotional wellbeing

Living with chronic pain can affect your mood and mental health. It is normal to feel frustrated or down. Talk to your doctor if you feel anxious or depressed. They can connect you with support, such as counseling or pain management programs. If you feel overwhelmed, reach out to a crisis helpline or call your local emergency number.

Prevention

While you cannot always prevent sciatica, you can lower your risk by staying active, maintaining a healthy weight, practicing good posture, using proper lifting techniques, and not smoking.

Complications

If left untreated

• Though rare, untreated sciatica can lead to permanent nerve damage, weakness in the leg, or loss of bladder or bowel control (cauda equina syndrome). This is an emergency.

Long-term outlook

The outlook for sciatica is very good. Most people feel better within a few weeks to a couple of months with simple treatments. Even if symptoms last longer, nonsurgical treatments are quite effective, and surgery is seldom needed. Working closely with your healthcare team and staying positive can help you recover well.
