Hi,
well I may not can exactly help you but I can tell you something that I have experienced!
Well I had the same thing happen to me.. Sore nippples and etc..
My breast hurt terrible even with my bra on .. Well I have no clue what happened there ( they are not hurting any more) but this happened about 2-3 weeks ago now!
The Dr. Put me back on birth control pills for 2 mth to make me ovulate so that may have something to do with all of that I done know.. But just to let you know.. U are not alone..
Hope that helps alittle...
