Lurking from Dec: I am a FTM, but I've had a lot of BHs. At first, they used to not hurt. Lately, they hurt and my stomach gets rock hard with no soft spots. For me, it usually happens when I get too dehydrated. I sit and make myself down multiple glasses of water before freaking out
(I just went through 4 painful ones in a row last night-- water fixed it!)
Before, when they weren't as strong, they would stop if I sat down and elevated my feet.
I just wanted to comment, because I am an example of painful, rock hard ones that still aren't real.
