For lower back pain and pain on one side of the buttocks and legs, if such symptoms occur, be alert to whether you have a lumbar disc herniation. If a lumbar disc herniation occurs, it will obviously compress the sciatic nerve on one side, causing pain on one side of the buttocks and legs, especially during coughing or sneezing, and sometimes can cause a pain like radiating from the buttocks to the back of the thighs and calves, like an electric shock. If this typical symptom occurs, it is mostly considered to be caused by a herniated lumbar disc. It is recommended to go to the hospital for a checkup after this symptom occurs, starting with an MRI of the lumbar spine, because a herniated lumbar disc can be clearly detected from the MRI. Sometimes it is also necessary to do electromyography of one lower limb to see the extent of sciatic nerve damage on this side, which is a great guide to determine the effect of surgery and treatment later.
