Does anyone have a recommendation for a doctor who treats chronic UTIs?

Miami resident for seven years. 47M. Standard symptoms. Burning during urination and ejaculation, urinating one to two times at night, occasional sharp pain in groin, and periodic vague aches in urethra. Cipro for three days and Bactrim for 7 days didn't work. Got relief from both medications after I took them but never ultimately worked.

My general practitioner gave me a quick urine test that was negative. The uro did the more comprehensive urine test. Both were negative. Blood was drawn for PSA and negative.

Uro has pretty much given up. Someone has recommended a MicroGenDX test, but that needs to be done in conjunction with a doctor.

Any recommendation you could provide would be helpful. Thank you.
