See a doctor. You only have one right arm.

If you have what I had, then it is "tennis elbow," which is caused by irritation (sort of like fraying) of the nerve that starts in your shoulder, runs through a hole in your elbow, and goes down to your little finger. Whenever you bend your elbow, this nerve slides back and forth inside the hole, and in time it may swell and begin to hurt.


I wasgiven a "brace", which was really nothing but a simple band with velcro on it. It firmed up the muscles around my elbow, and it did help. It was also suggested that I do exercises to strengthen my arm. I didn't do it, though.

It would be a good idea for you to rest your elbow. Take up some other instrument for a while.

BTW, I remember an article in Smithsonian Magazine in which a doctor said that the violin was an instrument designed to destroy the human right arm.
