Good day! Diarrhea since yesterday, had it three times yesterday. Gave Normobact. Today only once went and then again with diarrhea. No fever. But generally feels like a hot head. What do you recommend for diarrhea? After how many times should I be worried? Yesterday thought it was teeth giving me trouble, today such poos, think maybe caught an infection? All in all everything is pulling into my mouth.
