What should I do? I just ate a Pepperoni Hot Pocket and now my stomach hurts?

I was just playin' Minecraft like any other guy, when I decide I should get a hot pocket. I microwave and eat it… I go back to playing minecraft. Suddenly, I'm getting these horrible pains in my stomach, and I'm also belching and passing gas a lot. I walk over to the toilet and poop, thinking, Oh dang I bet it's gonna be a really big poop… But all that came out was a poop the size of a dime… Why is the Hot Pocket causing this? I don't have any allergies. And what should I do to make it better? My stomach Really is hurting, so please answer quickly!
I don't want a recommendation for medicine or going to the doctor… I don't want to waste money.

I might be the msg in them i'm allergic to the msg and i had the same feeling you did so i stopped eating them, i think you should do the same cause it was not fun for me. I hope this helped mayybe you could answer one of my questions
