Hip pain after intervertebral foramenoscopy may be caused by postoperative inflammatory nerve irritation, localized edema of the nerve root and other factors. 1. Inflammatory stimulation: intervertebral foramenoscopy surgery mainly uses the anatomical structure of the intervertebral foramen to loosen the compressed nerve root, and the surgical operation will cause local nerve tissue damage, which in turn will lead to an inflammatory reaction in the postoperative period. Inflammatory factors stimulate the nerve roots and cause pain in the buttocks and even lower limbs. Generally, the symptoms can be relieved after taking non-steroidal anti-inflammatory drugs such as bisacodyl or nutritive neurotropic drugs such as methylcobalamin. 2. Nerve root edema: Nerve root edema is mainly caused by aseptic inflammatory reaction after injury, postoperative nerve root edema can cause hip or even lower extremity pain and other uncomfortable symptoms, and also need to take non-steroidal anti-inflammatory drugs such as acetaminophen, bisacodyl, or nutritive nerve drugs such as methylcobalamin for symptomatic treatment. For the symptoms of hip pain after laminectomy, you can take medication under the guidance of the doctor and observe the recovery situation. If the pain symptoms continue to be unrelieved, further examination is needed to clarify the cause of the pain.
