Lateral buttock thigh pain may be caused by muscle strain, lumbar disc herniation, lateral femoral dermatitis and other diseases. 1. Muscle strain: muscle strain on the outside of the buttocks will cause small blood vessels to rupture and bleed, forming a local inflammatory lesion, swelling will compress the peripheral nerves, thus leading to buttock lateral thigh pain. 2. Lumbar disc herniation: Lumbar disc herniation will compress the sciatic nerve, which innervates the lateral buttock thigh, so it will lead to lateral buttock thigh pain. 3. Lateral femoral cutaneous neuritis: trauma can lead to blood vessel rupture, blood leakage, resulting in inflammatory lesions of the lateral femoral cutaneous nerve, which can lead to lateral thigh pain. Butt lateral thigh pain may also be seen in the dural tension inflammation, soft tissue contusion and other diseases, if the symptoms of butt lateral thigh pain, persistent unrelieved, need to consult a doctor in time to check the cause of targeted treatment.
