Diseases that cause nerve entrapment in the lower limbs include pyriformis syndrome, lateral femoral cutaneous nerve entrapment syndrome, common peroneal nerve entrapment, ankle tube syndrome, and common nerve entrapment syndrome at the base of the toes. 1. Piriformis syndrome: caused by compression of sciatic nerve, manifested as pain in one side of the buttock and leg and radiating to the lower limbs. 2. Lateral femoral cutaneous nerve entrapment syndrome: the disease is caused by the entrapment of the lateral femoral cutaneous nerve, manifesting as numbness and burning pain in the area innervated by the lateral femoral cutaneous nerve, and weakening of the senses of touch, pain and temperature. 3. Common peroneal nerve entrapment: the disease is caused by the entrapment of the common peroneal nerve, which manifests as pain and numbness in the lateral aspect of the foot and lower leg. There is also weakness in toe extension and weak or absent external rotation of the foot. 4. Ankle tube syndrome: the disease is caused by the entrapment of tibial nerve. Early manifestations are intermittent pain in the foot, plantar, with swelling and numbness, and the symptoms are aggravated after standing or walking for a long time. 5. Toe plantar common nerve entrapment syndrome: The disease is caused by the entrapment of the toe plantar nerve. There is burning pain below the toe bone, which is aggravated by wearing high heels, walking and standing. Symptoms of nerve entrapment in the lower limbs vary depending on the nerve and site of entrapment. If there are relevant clinical manifestations should be timely consultation, under the guidance of the doctor for standardized treatment.
