I have had bad diarrhea for last 4 days which sometimes has red blood in. I went to doctor who just said it was bacterial infection and I am on antibiotics. In the last 24 hours i am going less frequently but it is still like diarrhea. Does this mean the infection is getting better or should I go back to doctor? 2 days ago I was on toilet every 20 minutes for most of day, in the past 24 hours I have only been 6 times and the stool is less watery but still some blood
