I have lower abdominal pain and bloody stool. The symptoms started over a week ago when on a ski trip and eating food outside of my normal diet(from a sketchy little restaurant). I went to a doctor and it was diagnosed as enteritis, and I was given a shot(I assume it was penicillin), and medicine to take with meals. The medicine has run out and the symptoms are still present. I am an English teacher in South Korea and so I have some difficulties communicating with my doctor and cultural differences in terms of medical practices. I have hypothryoidism and probably celiac disease (any gluten intake causes diarrhea, so I avoid gluten). I m a 23 year old male.
