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.
If pressure is applied to these nerves, the pain will actually develop where the nerves go to (in this case, the hand). Herniated discs and nerve canal stenosis in the neck most commonly cause pain at the shoulder, thumb, second digit and middle finger. It is obvious that treating the hands will not help alleviate this pain since your hand isn't the root cause but merely a site of the symptom.
