Any ideas?

I woke up this morning with a pain in my stomach (or should I just say my left side of my torso area?), and it hurts mostly when I inhale even a little deeper than usual, like yawning, or when I was still in bed.

Last night’s dinner was one of those frozen Bertoli pasta mixes that you just throw in a pan, and garlic bread… both of which I’ve had several times before. I also had a Klondike bar.

I don’t think it’s something I ate, because it’s a sharp pain and not really in the “I just ate something bad” areas. As far as going to the doctor is concerned, I live and work 40 miles from my doctor and any emergency room is going to cost me an arm and a leg even with insurance, so I’d like to avoid it if possible.
