WHAT CAUSES JOINT PAIN

There are multiple causes of joint pain, among them, the common ones are arthritis, gout or injuries.
Osteoarthritis
Degeneration of joint cartilage and the underlying bone, most common from middle age onward. It causes pain and stiffness, especially in the hip, knee, and thumb joints.
Rheumatoid Arthritis
A chronic progressive disease causing inflammation in the joints and resulting in painful deformity and immobility, especially in the fingers, wrists, feet, and ankles.

Gout
A common form of inflammatory arthritis that is very painful. It usually affects one joint at a time (often the big toe joint). There are times when symptoms get worse, known as flares, and times when there are no symptoms, known as remission.
