the dr. never took a blood sample, any imagings, or gave me any examination. he asked what symptoms i had, i told him and said maybe it could be diverticulitis. then he gave me a prescription for two types of antibiotics. he never played one finger on me never did any tests and still made that diagnostic determination.
