Sciatica is relatively common among the general population. Its symptoms manifest as numbness, swelling, and weakness in one leg. The most common cause is herniation of the lumbar intervertebral disc, which compresses the nerve roots resulting in these symptoms. Therefore, when such symptoms occur, it is necessary to seek treatment at a formal medical institution. One could visit the orthopedics department, or if the hospital has specialized departments, it is best to consult the department of spinal surgery.
