What is Sciatica?
Sciatica refers to back pain caused by a problem with the sciatic nerve. This is a large nerve that runs from the lower back down the back of each leg. When something injures or puts pressure on the sciatic nerve, it can cause pain in the lower back that spreads to the hip, buttocks, and leg. Up to 90% of people recover from sciatica without surgery.
The most common symptom of sciatica is lower back pain that extends through the hip and buttock and down one leg. The pain usually affects only one leg and may get worse when you sit, cough, or sneeze. The leg may also feel numb, weak, or tingly at times. The symptoms of sciatica tend to appear suddenly and can last for days or weeks.
