Middle aged woman with chest discomfort but sort of changes locations, as well as comes and goes. Have always been healthy, no problems, etc. except for menstrual related pains since onset and even an endometriosis diagnosis quite a long time ago. Some stress related chest pain a few years ago with all tests fine but it feels different from that which was said to be anxiety related. Sometimes a bit of a burning feeling, heat etc. but recently, it is a bit like what I would imagine growing pains to feel like but in and around my rib cage/chest cavity. The bone areas in the middle can be sensitive to touch and discomfort in certain positions, even hurting while wearing a bra at times. It can also be felt up pretty high above the breasts sometimes. I did find a lump some months ago but it was non-malignant after a biopsy. I have a mole with some discoloration on my top right front of shoulder, near my clavicle, which has not been checked. I would appreciate any ideas of what this might be related to? Thank you very much!
