Pain that radiates from your lower (lumbar) spine to your buttock and down the back of your leg is the hallmark of sciatica. Occasionally, sciatic pain in men is caused by sitting on a wallet.
The sciatic nerve is the longest nerve in your body. It runs from your pelvis, through your hip area and buttocks and down each leg. The sciatic nerve branches into smaller nerves as it travels down the legs providing feeling to your thighs, legs, and feet as well as controlling many of the muscles in your lower legs. The term sciatica refers to pain that radiates along the path of this nerve.
