The left thigh neuralgia may be caused by the following reasons: 1. Vascular disease. For example, obstruction of reflux and stenosis of veins may lead to poor blood circulation in the legs and cause pain in the left thigh nerve. 2. piriformis syndrome. It is mainly due to the compression of piriformis muscle at the sciatic nerve, which leads to pain in the distribution area of the sciatic nerve, mainly manifested as pain in the rear of the thigh and the posterolateral side of the lower leg. 3. Lumbar spinal stenosis or lumbar disc herniation. It may cause compression of local nerves and blood vessels, as well as sciatica, which may further cause left thigh neuralgia. Therefore, when there is pain in the left thigh nerve, you should go to the hospital in time, and carry out symptomatic treatment after making a clear diagnosis through relevant examinations to prevent serious consequences caused by delayed illness.
