From time to time my nipples are frustratingly sensitive, but not that often. For me it is more of comfort to keep them from jiggling and keeping them off my chest. I have been wearing an athletic bra for about 2-3 weeks now and honestly, I feel 100x better. I also like that it hides my nipples, they aren't big, but they always seem to show thru my shirts....
I haven't been officially measured, but my wife's c-cup bra (I tried on to get idea of size) fits well, but the cup is a tad loose, so not quite a 40C. I have an XL Champion 2994 sports bra I found in black. I wouldn't mind a tad tighter, but not sure that is good to do, don't want to make it more visible by the skin being pulled in more and curves show up....
I was on bp meds for a while, lisinopril I think. Is that one of the meds that causes gyne? I am not on it now, I didn't get the script renewed and when I had surgery last year I had to have a cardiolist do a stress test and I passed with flying colors (yea!!). So no bp meds are needed per my dr....
To me it is a pain to need to wear, but sure more comfortable and improved daily life wearing it than not. But I am worried about how it will be when it gets warm out....
