The last couple of days around my abs/ribs feels really uncomfortable and swollen. It's not so bad sitting up with a bra on, without one my breasts rest right on it & it HURTS. I've only been able to sleep an hour or so here and there the last few days because it hurts so bad when I lay down. I'm a half on my stomach, half on my side sleeper and I can't be on my side or stomach at all.. it hurts too bad. Using pillows & even taking tylenol isn't helping. Any clue at all what this is?
