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.
Trauma or injury to the thumb such as a sprain or fracture can lead to pain and limited function. A âjammedâ thumb refers to a sprain of the ligaments surrounding the joint. In extreme cases, disruption of these ligaments can lead to instability of the joint. Overuse of the thumb is another source of thumb pain.
