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.
Sometimes, pain perceived in the thumbs is actually referred pain that originates from injury or disease elsewhere in your body. Depending on the cause, your thumb pain may be present in one or both thumbs. Osteoarthritis is among the most common causes of thumb pain, along with injuries and trauma. Deformities, either present at birth (congenital) or acquired later, can also cause thumb pain.
