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.
The most common cause of finger pain is a hand injury. Injuries to the finger can cause an open cut, a bruised or fractured bone, or muscle and tissue damage. Medical conditions that affect the nerves, muscles, or bones can also cause finger pain. For example, osteoarthritis causes the breakdown of cartilage, which is a tissue that cushions bones at joints. This breakdown causes bones to rub together and triggers pain and stiffness. In the hands, osteoarthritis can affect the joints at the base of the thumb, in the middle of the finger, and near the nail bed. A compressed or pinched nerve in the arm, wrist, or hand can also contribute to finger or thumb pain.
