Tendinitis, arthritis, fractures, sprains and a rotator cuff tear are common causes of pain in the arms and hands. Lacerations, injuries to the nerve or tendons, and tennis elbow are also causes, claims University Orthopedics.
Injuries to the peripheral nervous system are the most common causes of arm and hand pain. Carpal tunnel syndrome, radial tunnel syndrome and cubital tunnel syndrome are types of peripheral nerve injuries, according to the University of Cincinnati. A rotator cuff tear commonly occurs when the shoulder is overused, causing the joint to tear, says University Orthopedics. Tennis elbow is caused by overuse of the muscle surrounding the elbow. It causes tears in the muscles and ligaments surrounding the area.
