Undiagnosed Conditions

[cattlehead]

Starting in April, I had a acute onset of strange urinary symptoms, including burning while urinating, increased frequency of urinating, increased urgency to urinate. My mouth kept getting dry. I thought maybe I had a kidney stone or some type of infection.
These symptoms lasted about 2 weeks. The urgency and frequency returned to normal; however, the pain during and after urination remained, and my urine seemed to always be a concentrated yellow color no matter how much a drank, and it was also very foamy.

I informed my internist, who did a urinanalysis and kidney function blood work, both of which turned out normal. She referred me to a urologist

The urologist also did a urinanalysis and performed an ultrasound of my bladder. The analysis was normal, and the ultrasound showed that I was emptying my bladder completely. He tried me on rounds of Ciprofloxacin and Doxycycline, neither of which helped. He then did cystoscopy and found no anatomical evidence of anything wrong with the urethra, prostate, or bladder. He told me this chronic dysuria is difficult to treat and that we would have to wait for something to get worse in order to tell us if anything is wrong. He gave me some samples of Utira-C to try, but this doesn't help much with the pain.

I am not sexually active and have never been. I'm not sure what is causing this. I'm worried about my kidneys/ureter system because of occassional dull lower back pain and because my urine is always yellow (as opposed to previously being almost always clear) no matter how much fluid I drink. Where do I go from here? Should I see a nephrologist or just wait and see what happens?
