Hello, 2 days ago I had a bout of diarrhea, and intestinal pains. No nausea or vomiting (I so happened to have Ondansetron in my system, moments before the diarrhea issues started), but I did have intestinal distress the following day (no more diarrhea, though). Today however, I do have some breathing concerns. My intestinal distress decreased quite a bit, but when I breathe in, my breath/throat feels cold? I haven't drank much (about 45 ounces of gatorade yesterday, and... about 4 ounces total today), but I'm not sure if dehydration can cause shortness of breath.
