350cc/under the muscle/ sientra gummy teardrop/5'4 115 lbs I have been having sharp pain on sternum since 2wks post and a regular bra makes it so much worse, I think it's from them being pushed together ??Also I have a knot toward center of one breast. Surgeon said it's an inflamed rib joint but he didn't seem to know why I'm having the pain up and down my sternum. I had a thin/bony chest pre op. Wondering what's causing this and what I can do to help? Tired of sports bras and the pain :(
