Its a pain that comes and goes now for a few days, I cant tell if its in a muscle, or a bone or what. It is like 3 inches to the left of the hole there under your neck, that bone structure region. One bone seems a little bigger than the other but I think I've noticed that forever. I cant figure out where its from, im hoping from overuse at work, etc. Or a tendon or what no clue. Not terribly painful more annoying than anything, and anxiety triggering. I was feeling the bone so much under the skin yesterday that today it is sore.
