Hello, I Am A 51 Yr Old Female. I'm Not

Hello,
I am a 51 yr old female. I'm not sure what to do next . I went to the dr just after thanksgiving for what I thought was a UTI . She gave me a 3 day of Cipro. I finished that, and thought it was working, but no. Then I tried several days of a natural product called d-mannose, the sugar in cranberry. I had more relief from that, but not completely gone. I went back to the dr. She gave me a 3 day of bactrim. After 4 doses and no relief, I almost went to the hospital. During all this time, I also had crazy vulvar area burning, but not from the urinating. I had mild irritation with that. I've had 3 urinalysis(all normal), pelvic exam was normal, and vaginal culture normal too. At this point, I'm back to frequent urination, some back pain and pressure on left ab side, like it's ovary related. The 3rd dr wanted me to see a urologist. After lots of research, I think it's coming from menopause. This is the first time I've missed my period two months in a row. I also read that HSV causes this kind of thing too, and I get cold sores too. I don't know what to do. What do you think? I'd appreciate any help.
