Urgent: Stomach issues - Need help ASAP!

Since last Monday—so over ten days now—I’ve been dealing with this muscle tightness in my abdomen. I figured it was just related to my recent appendectomy, but an abdominal ultrasound came back completely clear. Then things took a turn on Wednesday; I started feeling nauseous and had this heavy sensation in my stomach. My gastroenterologist didn't think a gastroscopy was necessary yet, and then at the urgent care clinic, the doctor suggested it might just be some kind of stomach virus. He told me if it doesn't clear up, I'll need to go in for a gastroscopy. Things have improved slightly over the last three days, but I still haven't had a bowel movement. I honestly don't know what else to do.

Is it seriously impossible for anyone to have an answer, some advice, or even just a single thought on this?

I’m not quite following—you mean you're having an appendectomy soon? What did they have you prep for the surgery?

Are you on a specific diet right now? Maybe try sticking to just tea and toast for a day or two—nothing too heavy. If it’s just some kind of stomach bug, things should start looking up soon enough.
The last time I felt like this was when I was on antibiotics. Are you taking any meds at the moment?

I’m not scheduled for surgery until May 22nd, and I haven't been taking any medications or anything else. I think I'll probably need to get tested for H. pylori, and maybe even undergo a gastroscopy too.😢

Maybe it’s just some lingering effect from the surgery—did you have it done laparoscopically or was it an open procedure?
So, is the pain hitting your stomach or more in your intestines?
I remember one time my stomach hurt so bad I couldn't even move—it was brutal. I ended up taking some activated charcoal and it cleared right up. Honestly, it probably was just some bad takeout or food poisoning.
Just stick to a bland diet for a few days; if it's just a little bug going around, it should pass.

I had a standard procedure done, including an ultrasound and a physical exam by my surgeon, so I don't think it's anything major. It’s been going on since last Tuesday, so I’ve already ruled out a simple virus. Now I'm just terrified it's actually gastritis and I'll end up having to go in for an endoscopy.😢
