Thanks you very much for the answer. Any reason you can think of as to why my doctor would describe it this way instead of calling it a tendon and tendinitis? That seems so much simpler.
That "skin" you speak of is called a tendon. A tendon connects muscle to bone. The pain your feeling is from tendonitis -- an inflammatory process of the tendon -- and its treatment involves rest.
No, you should not be doing these activities as they will continue to aggravate your tendonitis.
