Stomach transplant please

Yeah, I know that it wouldn't make a difference, because it's pretty unlikely that this is a problem rooted in my stomach. But my stomach has hurt, to a greater or lesser degree, for about two weeks now. Sometimes it hurts more after I eat a meal, sometimes less. Right now, I know it's bothering me because I have Japanese lessons later today, but it was bothering me yesterday, and the day before that, and the day before that...

I'm set to talk to someone about it in the new year. We'll see if that helps, though me being me, I think the cost is causing even more trouble than it might end up solving.
