I got food poisoning friday night i did throw up and havent been keeping down much food. i was feeling better today until midway through i got some very powerful chills and now i am experiencing a fever of 100.2. is this part of food poisoning ?

Could be: It is not feasible to ascertain if your fever is part of food poisoning or a separate illness, without examining you. Take acetaminophen, no more than 4 g/day, no alcohol. If that does not resolve your symptoms, it would be prudent to see a doctor. Drink enough water so your urine is mostly colorless. Get HPV and Covid vaccines. Wish you good health!
