There are many clinical causes of hip and leg pain, and in order to treat it, we need to clarify what causes hip and leg pain, so that we can actively treat it symptomatically: 1, sciatic neuritis, which is common in clinical practice, can cause hip and leg pain, and for such patients, we need to actively apply anti-inflammatory drugs and nerve-nourishing drugs for treatment, and pay attention to rest and protection. If the patient has femoral head necrosis, it can also cause hip and leg pain. For such a patient, if the femoral head necrosis is in the early stage, it can be treated with crutches to reduce weight bearing, and with hyperbaric oxygen therapy or drilling decompression surgery. If the femoral head necrosis is more serious and has collapsed, which seriously affects the normal function of the patient, it is necessary to actively carry out total hip replacement surgery.
