I tested an intuitive theory I had and avoided having anything with dairy in it today. I believe I found the cause of a lot of my stomach pain and the other symptoms. I am lactose intolerant. I didn't have any of the symptoms that have been tormenting me for months.

But I also realized how dairy is in just about everything and how am I supposed to avoid eating it? I obviously need to do more research and possibly buy a cookbook especially for people who are lactose intolerant. But thankful I wasn't in pain today.
