Leg pain that travels from the back may be sciatica, doctors warn

The Story in Brief

Leg pain that starts in the lower back or buttock and travels down the leg may not be from the leg at all, it could be sciatica, caused by compression or inflammation of the sciatic nerve, experts say. The largest nerve in the body, the sciatic nerve runs from the lower back through the buttocks and down each leg. When a spinal nerve is compressed or inflamed, it can produce a sharp, burning, electric-like pain that radiates into the thigh, calf or foot.

Dr Kalidutta Das, chief and director of spine services at ISIC Multispeciality Hospital, warns that symptoms such as tingling, numbness or weakness in the affected leg, and pain that worsens after sitting, coughing or sneezing, should not be ignored. However, not all leg pain is sciatica, muscle strain, joint problems and blood vessel issues can cause similar symptoms. Severe pain lasting several weeks, trouble walking, or numbness around the inner thighs and genitals require immediate medical attention. Most cases do not need surgery and improve with rest, physiotherapy and proper medication.
