@hopeful33250 @imatine I had a blood culture done. I was surprised how quickly I got my results. I was in ER from about midnight to 3:00 AM. During that time blood was drawn for the culture. Then they sent me home. Just after lunch, they called me and told me I had to come back to be admitted to the hospital. They ran several tests and never found the cause. I had to have 15 infusions of antibiotics. I have not had problems with E coli since.
