Hi. my right arm feels cold and almost numb, not totally numb, just sort of heavy, like the skin is contracting. The feeling extends to my armpit, not really, the underarms, but that area that comes in contact witht the arm holes of my shirt. I can't stand anything tight around it. I had a massage yesterday and when my arm came in direct line of the car aircon, that's when the feeling started. Also last wednesday, i had another massage. The masseuse told me that there was something round on the right half of my back and that the same half side was slightly protruding than the other side. Please tell me what this could be.



thanks.
