I have a question. I have fibromyalgia . I found a lump in my chest not in my breast. Its kinda hard to explain where, bare with me please. ok its on the left side, if you were to take your right hand to place over your heart to say the pledge of allegiance. Do it, please ok look at your hand, the lump would be in between the pointer finger and your thumb. Like I said before its not in the breast. OKAY the question I have IS: I got scared went to the doctor and had a Mammogram done. The tech/ dr who read my films said it was a RIB! why would a rib be there????????? Help me. They made me feel like a id**t. Its more bother some and has gotten bigger???? Could it be a rib??? Thanks.
