So for the past 3 1/2 days I have not been able to eat anything without rushing to the bathroom a few minutes later. I am scared to eat because of it. I'm having back cramps and think I have a fever. And my tummy growls but right below my ribs so that's wierd... I'm thinking I should go to the Dr just to get checked to see if I'm dehydrated. I look everything up on Google and it said 3 or more days with diahrea to go to the Dr.
