Common causes of hip pain:
- Osteoarthritis is a condition of joint erosion, which eventually causes cartilage and bones to collapse in the hip joint. In this case, the bones in the joint are rubbed against each other, causing pain in the hip joint in each movement.
- Autoimmune arthritis, in which the body’s immune response adversely affects the joint membrane called the synovial membrane, causing chronic inflammation and pain in the hip joint. The synovium becomes thick, inflamed, and painful. In this situation too much synovial fluid is produced inside the hip joint, causing chronic inflammation that causes cartilage loss, pain and stiffness of the joint.
- AVN is a condition, when the bone does not receive its normal blood supply. Without adequate blood input, the bone structure is weakened and may collapse and damage the cartilage. When this happens at the top of the femur, this causes destruction of the hip joint.
