Yes, I have finally heard back from the doctor. All my blood tests, x-rays and ultrasound were normal. There's nothing wrong with me. So, why do I have this excruciating pain in my stomach? I don't know why. I guess it's not really there.
There is some speculation going on, however. The nurse told me that the doctor thinks I have IBS, to which I was going to respond that IBS is a load of bull. I mean, really, it's a symptom, not a problem. Tell me what's really wrong with me. Apparently there's some weird thing where food doesn't go through one's digestive system quickly enough and it causes pain. It's not IBS, so that makes me happy. The answer to the problem can be found in a high fiber diet and lots of exercise. Well, at least it's not a ton of nasty medications.
I think the moral of the story is that my stomach hates me.
