I think I came out from food poisoning the other day... I had diarrhea,vomiting,chills,dizziness and it went for a whole day last Tuesday...now i just feel bloated and gassy...and the gas is more untolerable than my usual gas leak...I also feel like I m having high blood, but when I check my bp it s normal... I have some back pain, but I don t think it s related to what just happened to me. My question is, is there a reason why I m gassy after recovering from diarrhea?
