Chest wall pain above breast

I am an athletic 42-year old female, workout 6x/week running, pilates, biking, and weight training. I have experienced right sided chest wall pain 1" above my right breast for 2 months. The pain is in a small area, about the size of a half dollar. The pain is felt when pressure is placed on the area. Cannot feel any lump. I have no shortness of breath, difficultly breathing. Had a mammogram and breast ultrasound, which both came back normal. My doctor prescribed NSAID, which did not help. My doctor is not concerned, says I am fine. Any suggestions on possible diagnosis? Should I encourage him to order additional imaging studies??

Yes, ask for more testing if your still having pain. If your Dr refuses to, then see another Dr.
It could be muscle pain or even a rib out of place but you need to find out what's going on. Take care. Remar
