About a week ago, I experienced chest and stomach pain at the same time. The next day I noticed there was a hard, bony pronounced bump on my chest, above my breasts, closer to my heart . My chest no longer hurts, however the bump or lump is still there. It doesn t feel like tissue , but like a hard bone, resembling a circle or oval. I also have a thyroid condition and not sure if this is related to my current situation. Also, my primary physician is currently on vacation. Do you have any answers that might help me?
