I have had diarrhea, cramping, nausea, vomiting for 5 days - fatigue - basically bed and bathroom. Am out of town on vacation. Went to an urgent care facility and was diagnosed with gastroenteritis and prescribed nofran. Symptoms persist. I have never had this kind of problem for this length of time, I had a prostate biopsy 3 weeks ago. Had some mild loose stools in the am for a few days but nothing serious. Urologist does not not think this is an infection from that procedure due to length of time, I a 62 year old male. Very fit. Trying to figure out what is going on with me.
