I have been having diarrhea a day after I ate some chinese food. Along with it came a fever a headache, stomach cramps, weakness of muscles, shortness of breath, and continuous diarrhea. Then the next day I vomited 2 times then I felt better. I started to eat soup. The following day I had to call out of work because I still have diarrhea. I was wondering if its a case of msg a virus or a stomach flu?
