Hello, my friend recently just had food poisoning. He has vomited twice since. Now he is saying he feels cold inside, has a headache, whole body aches and its sore to touch, muscle and joints hurt, gets dizzy if standing to long, and has been falling asleep on and off all day
Thanks for your question on Chat Doctor. I can understand your concern. Food poisoning causes gastritis, vomiting and diarrhea. Vomiting and diarrhea causes loss of fluid and electrolytes (sodium and potassium) from the body. Gastritis and vomiting cause less appetite and decreased oral intake. So overall patient is deny Chat Doctor.  These can cause all the symptoms like headache, generalized body ache, muscle and join pain, giddiness, sleepiness etc. Best treatment for this is oral rely
