Jumping pain in the root of the right thigh on the ninth day after minimally invasive surgery for lumbar disc lumbar five sacral one herniation may be due to nerve damage during surgery or that pain is not related to the primary disease. 1. Surgical injury: If the nerve is damaged during lumbar disc removal in minimally invasive surgery, it may lead to physiologic disorders of the nerve, nerve edema, and increased excitability of the nerve, which may lead to throbbing pain in the lower extremity within the coverage of the nerve. 2. The pain is not related to the primary disease: a throbbing pain in the root of the right thigh is not an obvious symptom of the primary disease or complication, and there is no direct evidence that the throbbing pain in the root of the thigh is related to the surgery or lumbar disc herniation, and may be due to pain caused by compression of the nerves in other parts of the body. On the ninth day after minimally invasive surgery for lumbar disc lumbar 5 sacral 1 herniation, the throbbing pain in the right thigh root may also have other causes, such as muscle injury, venous embolism, etc., and should be promptly consulted for a clear diagnosis and targeted treatment.
