Anyone else?

So i just finished dinner about 10 minutes ago and i had a chocolateshake a small one and shortly after eating and drinking by stomach started to hurt and i got gassy then had to run to the bathroombecause of the pain and feeling like a volcano was going to erupt. Dont get me wrong i suffer from ibsu , endometriosis, and cryonic dehydration but i havent felt bad or been sick like this for almost a year and then all of a sudden boom this happens . So does this happen to anyone else have to deal with this or know what i can do to prevent this.
