Sciatica: What to know about the common condition

Sciatica is a common condition characterised by pain that radiates along the path of the sciatic nerve, which runs from the lower back through the hips and down each leg. Rather than being a diagnosis itself, sciatica is a symptom of an underlying issue affecting the nerve, most often a herniated disc, spinal stenosis, or bone spur compressing part of the nerve.

The hallmark symptom of sciatica is a sharp, burning, or shooting pain that typically affects one or both legs. This pain can range from mild discomfort to severe, debilitating sensations that make standing or sitting difficult. Other symptoms may include pins and needles, numbness, tingling, or muscle weakness in the affected leg or foot. 

Risk factors for sciatica include age-related changes in the spine, obesity, prolonged sitting, and occupations that require heavy lifting or twisting movements. Poor posture and a sedentary lifestyle can also contribute to its development.

Treatment for sciatica often begins with conservative methods. Rest, gentle stretching, physical therapy, and over-the-counter pain relievers can help reduce inflammation and relieve pressure on the nerve. Applying heat or cold packs may also provide symptom relief. In more persistent cases, doctors may recommend prescription medications, steroid injections, or, rarely, surgical intervention to address the root cause.

The natural history for sciatica is one of spontaneous resolution with approximately 70% resolving by 6 weeks and 90% by 3 months. During this time, managing the pain and trying to remain as active as 

Preventing sciatica involves maintaining a healthy lifestyle. Regular exercise, especially core-strengthening routines, supports the spine and reduces strain. Practicing proper lifting techniques and maintaining good posture while sitting or standing are also essential.

Although sciatica can be painful and disruptive, most cases improve with time and non-invasive treatment. Early attention to symptoms and healthy habits can significantly reduce the risk of recurrence.
