Severe pain

Anyone have any advice, or know what’s possibly causing this? So about 1 month after birth I went to a restaurant and had a big salad, came home had SEVERE pain. Felt similar to labor!! Then I puked all the salad up, had pain again for a little bit, then finally it went away...So I thought it was everything going back to normal after my birth..Fast forward to a few months later..One night I ate some hot wings with ranch, and again SEVERE pain, threw up, more pain, then went away, that time a little worse, I got super dizzy after the pain was gone, was sweating a ton, felt like I was going to pass out. I had to sit down in a cold room, and breathe for a minute..well now I’m feeling like that pain was about to come so I took 4 ibuprofen (2 about an hour ago and 2 just now) and some acid reflux meds because the doctor, and hospital told me that’s what this pain is..🤔🤔 I don’t think acid reflux is supposed to be EXTREMELY painful. I felt like I was literally dying the 2nd time it happened. I have also noticed the pain happens after my period which I don’t get often because I’m breastfeeding. Sorry this is so long, but I’m super worried about what this could be.

Update for anyone reading, it was my gallbladder, and I had my gallbladder removed...no more pain!
