On Monday 5/17, I had watery diarrhea all day. Later that night, I started getting fever and chills with an oral temp of 101.7. I tested negative for COVID and the fever mostly resolved in the morning so I left for vacation to Mexico. On Tuesday, 5/18, the fever was mostly gone but I still had diarrhea throughout the day. I took half of a Pepsid and Dayquil which helped a little with general malaise and the GI problems. Tuesday night I went out to dinner and had 3 drinks and felt alright until I got back to the room and had more diarrhea. On Wednesday, 5/19, I felt very bad in the morning, now with constipation. I had severe urgency but when I tried to have a bowel movement nothing except a few drops of blood came out. I drank a lot of water and got Pepto-Bismol and an anti-diarrheal called Treda (neomycin-sulfate). I took pepto and drank a lot of water until I had a BM, then I took a Treda which helped. I had two drinks during the day. Later returned to constipated with more blood. At night had a large BM followed by more urgency and constipation. Today felt better but ate breakfast and immediately had diarrhea followed by urgency and constipation again, but less blood today. I am supposed to come home on Tuesday, 5/25, but am wondering if I should come home earlier. The options are to stay and not drink or eat anything that might exacerbate the symptoms and see a doctor on Wednesday of next week; see a doctor here (not close by); get antibiotics at a pharmacy; or change my flight home to Saturday, 5/22 (complicated and expensive but do-able). If someone can please give some advice on how much of an emergency this is and what the best course of action would be, I would be beyond grateful. Thanks.
