Does surgery lead to persistent neuropathic pain
True. Surgery causes either direct nerve injury through severing during surgery or stretch during retraction. In some patients scar tissue formation may also cause nerve compression. Inguinal hernia repair may lead to persistent groin pain due to inguinal and/or iliohypogastric neuralgia and/or genitofemoral neuralgia. Spine surgery may lead to “failed back syndrome” or “postlaminectomy pain syndrome,” which is a well-described phenomenon, particularly after laminectomy, that may involve neuropathic components or nerve injury. Orthopedic surgeries can also lead to various peripheral neuralgias, depending on location and in some instances CRPS, type 2.
