I previously had a GI E. Coli infection in August. I was hospitalized for 2 days with dehydration and diarrhea. I had another stool sample completed in December. I still showed elevated levels of E. Coli in my gut. Recently I was out on 10 days of amoxicillin due to dental work. I completed the antibiotics approximately a week ago. The severe cramps, nausea and some diarrhea have returned abruptly today. Is it possible for the infection to flare?
