Sciatica refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg. Typically, sciatica affects only one side of your body.
Sciatica is usually caused when a herniated disc or bone spur or slipped disc in the spine presses on the nerve root. Pain originates in the spine and radiates down the back of the leg, usually affecting only one side of the body.
Treatment commonly includes use of medication for the pain as well as physiotherapy. In severe cases, an epidural injection may also be recommended.
