I had the stomach pain twice yesterday for a total of 10 hours.

I'm going to the hospital today to see if they can find the cause. There's no pain now so I'll likely be there for a long time, but at least they'll be able to do all the tests while I'm there.

TMI warning...

I'm kind of worried, I think I have blood in my urine. I have been taking Tylenol 1 though and I read that is a rare side effect. Hopefully that's it.
