Hand pain, also called hand cramps, can be associated with a number of underlying medical conditions. The most common cause of hand pain is overuse or injury to the muscles and bones that control movement in the wrist and fingers.
Examples include lacerations, fractures, tendonitis, arthritis, nerve compression syndromes, bursitis, and carpal tunnel syndrome.
There are many causes of hand pain, but overuse is the most common cause. Hand pain can be associated with any condition that causes muscles or bones in the hands to become damaged or diseased.
