I have a knot in my back and from looking at anatomical pictures it looks like a tendon that hurts.  It hurts when I touch it and it "clicks" when I move my arm a certain way and when I do exercise.  Should I stop exercising?  What kind of doctor should I see?  How would tendonitis be treated if that is the cause?  Thanks
Thanks, I do go to a gym, and that’s how I noticed the problem.
