Arthritis, Osteoarthritis and Rheumatoid arthritis are among the most common causes of hip pain, especially in older adults. Arthritis leads to inflammation of the hip joint and the breakdown of the cartilage that cushions your hip bones. The pain gradually gets worse.
As people age, hip bones can become increasingly fragile, so it is important to seek help if your hip is causing you pain or you are havign trouble being able to move it. People with arthritis also feel stiffness and have reduced range of motion in the hip.
