Necrosis of the femoral head can soak the feet, but soaking the feet may only reduce a certain degree of pain, for necrosis of the femoral head does not improve. Necrosis of the femoral head refers to the interruption or damage to the blood supply of the femoral head, resulting in the death of bone cells and bone marrow components, followed by the continuous repair of bone cells, ultimately resulting in structural changes in the femoral head, causing the collapse of the femoral head, joint dysfunction. Pathology is caused by trauma resulting in femoral blood red damage, or long-term use of hormones resulting in bone tissue lesions, or chronic alcoholism resulting in impaired regeneration of bone tissue. Foot soaking can only improve the blood circulation of the foot, release muscle spasm, relax muscles and relieve pain. However, it cannot improve the blood supply of the femoral head, and cannot fundamentally treat necrosis of the femoral head. Necrosis of the femoral head is recommended to be actively consulted and treated under the guidance of physicians.
