Hi, My symptoms include vomiting,diarrhea, headache weakness belly pain and chills. 4 of us living under the same roof are having the same symptoms. My cousin along with her boyfriend and 15 month old baby who live separate from us are having the same issues. I want to think that it is food poisoning, but my cousin and her family having the same symptoms did not partake of take of the same food as us. Doctor, what do you think the issue is?
