Ouch.

That belly button muscle pull is still plaguing me. I didn't know that there was a muscle there. Well, I've seen a picture of it on people with a six pack, but on myself, I had no idea it existed. It does, and I tweaked it. I'm not sure how long it will take to heal, but it does hurt. Rubbing that area helps, also ice and a pain killer. Hopefully it will pass soon, standing up straight is once again painful.
