Sciatica: Understanding the Symptoms and What Helps
True sciatica is a symptom, not a diagnosis. A plain-English guide to what causes it, what to do at home and when to seek help.
Sciatica is a term used to describe pain that radiates along the sciatic nerve — the longest nerve in your body, running from the lower back down through the hips, buttocks and legs. It's not a condition itself, but rather a symptom of something irritating or compressing the nerve. Many people experience sciatic discomfort at some point in their lives.
Sciatica refers to a set of symptoms rather than a single diagnosis. It usually occurs when part of your lower spine or surrounding tissues put pressure on the sciatic nerve. This can happen for various reasons — spinal discs bulging or degenerating, wear and tear in the joints, or temporary swelling around muscles and ligaments.
Common symptoms include pain radiating from the lower back to the buttock, thigh or foot (sharp, burning or aching); numbness or tingling in the leg or foot; weakness in the muscles of the leg or foot; pain that worsens when sitting or standing for long periods, or when sneezing or coughing; and difficulty moving or controlling the leg or foot in more severe cases.
Causes include herniated or slipped discs, spinal stenosis (narrowing within the spine), degenerative disc disease, piriformis syndrome (a tight muscle deep in the buttock irritating the nerve), pregnancy (changes in posture and added weight), and poor posture or prolonged sitting.
When to seek help: book in if your pain lasts more than a couple of weeks or keeps returning; if it interferes with daily activities like walking, sleeping or working; if you notice increasing numbness, weakness or difficulty controlling your leg or foot. If you experience bladder or bowel changes, that requires urgent medical attention — go to A&E.
Self-care tips. Keep moving gently — long periods of bed rest can make things worse. Apply heat or cold and see which feels better. Mind your posture — avoid slouching. Avoid prolonged sitting and get up regularly. Try low-impact exercise like gentle swimming, yoga or Pilates.
How osteopathy may help. An osteopath will use gentle manual techniques to release tension in muscles and connective tissues (helping reduce pressure on the sciatic nerve), improve joint mobility in the spine and pelvis, and support healthier posture and movement patterns.
