I have had repeated u.t.i.'s and have had five in as many months. ive had antibiotics and the last test was clear but the doctor has requested an ultra sound scan. I do not know why or what they are looking for and i am extreamly worried about it. I am still getting sharp pain in my pelvis on and off and back pain above my hips, sometimes one side sometimes both, the pains come and go, some days i dont have it at all, very faintly. I do not have any other symptoms, i.e. pain on weeing etc. as i did before tabs. I have also started to take cerezette contraceptive pill , im in my fith week, could these cause the pain?
