How do you tell food poisoning apart from appendicitis?

disclaimer: i have pretty bad health anxiety.

the only thing i had that my boyfriend didn’t were some noodles that i now think may be the culprit.

about an hour ago after sex, i started getting terrible stomach cramps along my lower abdomen (not localized). went to the bathroom, got crampier and some chills. definitely a bloated feeling overall. did the push test on my lower right side, but no pain as much as i just have this general annoying dull ache everywhere.

internet can’t tell me if i have food poisoning, burst appendix, or both.
