question: I have been on antibiotics for about a month for sinus infection and Dr. thought I had a UTI because there was blood in my urine.  For the past 2 wks I have had buring in my stomach and chest.  Had blood wk my liver enzymes were elevated.  Dr. said wait about a month and we will check your blood again.  I really do not want to wait my stomach burns with pain everyday.  Any idea??
