Hello, i have had a pain not in my breast tissue but its beside my breast imbedded in the tissue beneath it to left handside. I have read many others here have this too, my sympathy goes out!  Ive had this since 2015, so 5 years now & still concerned about it. Ive had mamograms which were excruciatingly painful & made me yell out when this breast was pressed & i wondered if my breast muscle was ripped... result was no sign of cancer but to be honest this isnt in the breast. I have autoimmune problems 20 yrs & dr said it was probably another autoimmune condition & an inflamation of the rib cartilage. Theres one particular spot which hurts. Ive large breasts & removed the metal bone that side. It aches all the time & im at a loss what to do. Any advice id be so grateful. I feel the dull pain has increased & i can feel it through to my shoulder blade
