The nerve in the leg has been damaged, depending on the extent of the damage. Some can be recovered, such as a strain injury to the nerve, and some are very difficult to recover, such as a complete rupture of the nerve. Different treatment options can be chosen depending on the damage to the nerve. If the nerve is stretched, the continuity and integrity of the nerve is good, you can usually choose conservative treatment, acupuncture, electrical stimulation, and nerve-nourishing drugs, such as methylcobalamin and rat nerve growth factor. If the nerve of the leg is traumatically broken, it needs to be actively repaired by surgery, postoperative auxiliary plaster fixation for four weeks, together with nerve-nourishing drugs, such as nerve growth factor, and other treatment, and active functional rehabilitation will help the recovery of nerve function.
