Organomegaly involves the enlargement of body organs. Many different factors may cause such enlargement. While some causes are benign, others are more serious. Heart enlargement, liver enlargement, and spleen enlargement â called cardiomegaly, hepatomegaly, and splenomegaly, respectively â represent three examples of abnormal organ enlargement.
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.
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.
