Excessive wear of the thumb joint over time can lead to a break down of the joint cartilage causing inflammation and potential osteoarthritis of this joint. Excessive activity can also lead to inflammation of the tendons surrounding the thumb joint. Rheumatoid arthritis can also be a cause of thumb pain. If the tendons around the thumb become inflamed, tendonitis may occur leading to pain around the thumb joint. Another potential source of thumb joint pain is carpal tunnel syndrome.
