Anyone else get real bad stomach ache

That doesn't sound good.

Just random throwing different ideas out

Appendix issue

Bowel blockage

A internal tear where there shouldn't be

You ate something that didn't agree with your body for some reason (could be many different reasons).

Not enough information to target what it could be, but there are a lot of possibilities, and not all of them as bad as these, but if you have an internal tear, you probably need to see medical people. But it might not be that at all, hard to tell.

PS: I just research stuff, I have no medical background, and medical advice should not be taken from me.

Hmm not typically. If it's just once of any health concerns I typically just keep an eye on it but if it occurs regularly...( Tummy aches, bleeding, headache, whatever may be) I try to see a doctor.

You might have
a) ulcers
b) some intestinal issue

Either way bleeding from where the sun don't shine is a doctor visit. At your age it might be something worse so get it checked.

Yeah but I don't bleed. I've got diverticulum, and I get to go have a colonoscopy in about a month because of it.

What are you doing asking us on here?

Please be seen ASAP by a doctor.
It can be so many things; blood generally isn't good.

*Go and take care of yourself*.

Did you eat tomatoes? Highly acidic and very colorful on the way out

Did you eat something that went bad ..to cause stomach ache? Or was it from a bug maybe?

Go to the ER

Maybe go to a doc or the ER instead of asking a random site on the net

No I don't. I would highly suggest you see a doctor.
