Hi, I have had sudden onset diarrhea for 4-5 days, generally in the first two hours in the morning.I have eliminated things from my diet, but have not been able to identify any specific triggers. I have mild flu symptoms-muscle aches, mild headache. I have kept myself hydrated and am drinking electrolyte drinks. I am not sick enough to stay in bed. Several other people in my acquaintance have similar symptoms.I am not inclined to go to the doctors yet, but do not want to neglect a situation that might be serious.Any suggestions would be appreciated.
