Hello, I am quite concerned as I just got extremely sharp pains in my stomach that came in pulses (as in contractions or childbirth) and made me rapidly get a fever, sweat, see spots, shake, and feel like I was going to faint. Diarrhea began but was very painful on the inside. I became extremely nauseaous and got mucus in my mouth with gagging, but did not end up vomiting. I used to get a fraction of these symptoms when eating dairy, but i did not eat dairy and nothing was ever this bad. Please advise.
