Hi, may I answer your health queries right now ? Please type your query here...I haven't been well for the last 4 days, started with feeling very tired then very cold with shakes, then 24hrs after that diarrhea started, I have had this noe for nearly 48hrs. Have taken Codeine, which helps for a while, about 1hr ago started taking diarrhea tabets, which don't seem to have helped. I get pains in my stomach just before I have diarrhea.
