I hope it is "nothing much."
Sometimes we just move the wrong way and we get an owie. I went to Urgent Care Wed. night because my ribs were so painful. Turns out I have a "chest contusion", fancy words for a strained muscle. Probably from doing slams with the 30 lb ball on Saturday. BUT it was so much fun! I got a prescription for painkillers, so I can sleep at night. He give me enough to be them during the day too, but I'd rather not. The doc said I could do whatever exercise didn't hurt. It hurts to pick up my Tubby Tucker Cat though.
