Question: I had a uti in XXXXXXX Keflex didn't eradicate it. Took macrobid and urine was clear on dipstick for a couple of months even though minor urethra and vaginal irritation continued. Started using vaginal estriol cream (I am 64 year old, post menopausal). Symptoms increased a bit, still not horrible, in September. Had white cells on dip. Took macrobid 2 weeks. Again clear urine dip and symptoms reduced but not totally gone. Now it's back again. Cultured it and ecoli is present. Symptoms still relatively minor... Urethra and vaginal irritation is main symptom and that is off and on. This time the Dr put me on one week macrobid with change to ampicillin afterthat... Low dose, 250 mg 3 times a day dfor 6 weeks. I hate to take antibiotics and just wondering of that sounds Okay. I don't understand where this is coming from and I worry alot and am pretty scared. I'm not sexually active either. I use cranberry tabs and d-mannose and other anti inflammatory supplements and drink lots of water. Sometimes I don't feel anything. My doctor thinks there may be an access in the bladder, which is why he is treating long term. But I don't see anything on the internet to even suggest that possibility. Also, my sister is deathly allergic to penicillin so I have always refused it. Dr says that is not a valid reason and it is the safest. I'm also worrying about cancer. But Dr said my urine showed normal amts of epithelial cells and rbc so he says that shouldn't be a concern. Please help... I'm really nervous.... Can't sleep

You didn't really answer my question about the course my Dr prescribed or the penicillin etc or bladder abscess. I do all those things you said. I've never had diabetes and there's zero sugar in my urine now. I don't have ins so shouldn't I do other things before ultrasound? I don't have any pain like there's stones. I had an ultrasound Yeats ago when I was having utis and I was structurally normal then. Don't know of that changes
