question: I think i might be lack toast and tolerant, but i m not too sure. I ve noticed that recently for about a few weeks, whenever i would have milk, milkshakes, or mac and cheese, i would get bad stomach pains. Sometimes the pains would last about 30 minutes, but at other times diarrhea comes with it. For example yesterday, i had a milkshake, and when i got home, my stomach hurt badly. And this morning i ve had alot of gas to go with it. I m not sure if that s what goes with it, but could you tell me if what i m saying sounds like i have it, and/or if i should go get a test?
