hello, yes Hi, may I answer your health queries right now ? Hi, I had cystitis about 3 weeks ago with blood in my urine also, the doctor prescribed co-trimoxazole as a Blind Therapy she said. I took them for 3 days whilst I was waiting for the urine test result, however I got worse and uncomfortable pain on my right flank (beneath the rib cage and to the side) The results showed that I had indeed a bacteria : E Coli, which was not in fact sensitive to co-trimoxazole. By which time, I couldn’t breath properly feeling uncomfortable pressure now on both sides. Anyway, this other doctor gave me cefixime 400, 1 to be taken daily which I took for total of 17 days., and the result of the sonography was that I had Mild Stasis in both pelvocaliceal systems, more prominent in right side, which it said could be anatomic or due to overhydration or mild infection/obstruction. After having taken the Cefixime for the 17 days, a few days went by and I got sick, vommiting and diaorrhea, still this pain on the right flank., also general feeling of malaise and continuous dry mouth, during the day and night. I would also like to stress that I am 52 years old, take levothyroxine daily for underacive thyroid. I would most appreciate your help and advice.
