re: I thought I was going to die last night. Wtf is wrong with me

I have had this same pain twice in the last year. Exactly like you said: front left side, bottom ribs to the belt. It felt like hell, but I wasn't dieing. I was still able to fall asleep. I might have a high pain tolerance, I don't know.

I did the googling and it returned all the same things. Diverticulitis, gas. I originally thought appendix too but i didn't seem to have those symptoms and or kidney stones symptoms either. I chalked it up to either gas or constipation, but I never took a huge dump or ripped a big fart. It just ended up passing.
