Hello. My husband, son and I all ate fish from a fast food restaurant on Thursday. On Friday, I had diarrhea over the course of the day with some abdominal pain, weakness and fatigue. I felt better by that evening. My son was a little nauseous on Friday night, but felt better with Pepto Bismol and tums. My husband became feverish with chills, severe weakness, and severe diarrhea on Friday evening. He has continued to feel weak since then with diarrhea and some nausea. He has no appetite. I have been offering crackers, soup, ginger ale, and popsicles. He is very tired and has been sleeping most of 2 + days. He does not think he needs to see the Dr. ..... He is diabetic (oral meds) and is being treated with hormones for prostate cancer. Thank you for your help.
