Why does the area between my elbow and my shoulder hurt so bad? sometimes i have to drop what i'm doing bcuz it hurts so bad..for about a half a year

Tendonitis/Bursitis: The most common modern day diagnoses are related to computers and keyboards. An over use syndrome develops that will not heal with out resting the arm or shoulder that is hurting. Often a person must rest the muscles for two weeks. That means no repetitive motion or keyboarding. I often put patients in arm slings to remind them to rest this arm.
