Thumb pain can result from damage or injury to any of the structures in your thumb, including bones, joints, tendons, nerves, muscles, blood vessels, connective tissue, skin or fingernails. The symptoms may be constant or they may vary, and they may improve or worsen with movement.
Alternatively, with excessive activity, there is a chance that you will develop inflammation to the tendons around the thumb joint. Rheumatoid arthritis is another potential cause of thumb pain. When the tendons around the thumb get inflamed, you might develop tendonitis which will lead to pain around the thumb joint to develop. Carpal tunnel syndrome is another potential source of thumb joint pain.
