In the clinic, if the patient has thigh pain when lifting up, it may be that the patient suffers from lumbar intervertebral disc herniation. As the patient can pull and stimulate the lumbar muscle tissues when lifting the thighs, the pressure in the spinal canal increases, which can stimulate the sciatic nerve or compress the nerve root, leading to the patient’s thigh pain phenomenon. It can also be accompanied by radiating tingling in the lower limbs or localized skin sensation loss, muscle strength reduction and other clinical manifestations. In addition, if the patient has a muscle injury to the quadriceps muscle group or biceps muscle group in the thigh area, when the patient lifts the leg, it can also stimulate and pull the injured muscle tissues, resulting in localized pain phenomenon. If the patient has iliotibial bundle contracture or fasciitis, bursitis and other diseases, when the patient lifts the leg can also stimulate the local foci of the disease so that the patient produces pain.
