Thanks for your query at HCM! I see you are quite troubled. I suggest you to be brave and take correct treatment. How have you been treated in past? Are you diabetic? I suggest you must collect clean catch mid-stream sample and send for routine microscopy and culture & sensitivity for bacterial infection. You must take take the treatment based on sensitivity report. I suggest one must look for a source of persistent infection, such as a structural abnormality (eg, stones, renal abscess, cystic disease) for which is you need investigations like ultrasound abdomen & Pelvis. It has been seen that postmenopausal women who have recurrent UTIs may benefit from estrogen replacement, either systemic or local. Practice to void urine immediately after intercourse. Take care!
