Leg pain after lumbar protrusion surgery is usually not normal. Symptoms of leg pain after lumbar protrusion surgery are associated with local hematoma formation, edema in the surgical area, and nerve edema. A common cause of lower extremity pain symptoms is edema of the nerve fibers after the nerve root is released from compression. After lumbar protrusion surgery the symptoms of leg pain usually return to normal as the hematoma is absorbed. Only in rare cases, there may be some damage to the nerve root and there will be symptoms of leg pain. Leg pain after lumbar protrusion surgery is generally considered to be a symptom of nerve irritation, or caused by some degree of nerve root irritation during surgery. In addition, late movement after lumbar protrusion surgery, which leads to nerve adhesions, can also cause leg pain. It is recommended to go to the hospital for an examination to determine the diagnosis and results, choose the appropriate treatment and avoid excessive exercise and rest.
