Anyone dealing with prolonged gastroenterological issues for last 2 months?

I've been dealing with persistent lower-abdominal/stomach pain for around 2 months now.

I was on a long business trip for around 4 months, staying in a hotel. Since hotel food was too expensive and honestly not worth the price, I was ordering food from Swiggy/Zomato almost every day.

At one point, I ordered two small Pizza Hut pizzas through Swiggy at around 4 AM on a weekend. It was raining that night. When the delivery guy arrived, I noticed that the zip on his delivery bag was open. The pizza box was slightly wet on the outside, and the pizza was cold as hell. It also seemed like the pizza was either very old or undercooked.

I ate it anyway, and 3-4 days later, my abdominal symptoms started.

I've had persistent lower-abdominal/stomach pain since then, for roughly 2 months. Eventually, I rushed back to my hometown from the business trip because of all this, and I've been dealing with the symptoms since.

I also came across this reel recently:

So I'm wondering, has anyone else here gone through something similar?

If you had a suspected food-borne/viral illness and developed prolonged GI symptoms afterward, did you eventually recover? How long did it take?
