Aw, Erin! Sorry you jinxed yourself. I have been going braless all week. I just can't get that dang thing back on. Even went to the dr. without one, which it is very rare I ever leave the house without. It just irritates that nerve so much.
I have heard sports bras are actually very comfortable. I don't have one so I've never tried one. I try to get bras that have a soft and comfortable band. I have yet to try one of the foam ones but am seriously thinking about it.
I hope your side starts feeling better soon.
