Prostate infection, doesn't have to be an STD, but can be. An exam with your doctor, and possible antibiotic treatment can be an option for treatment.

Your symptoms are suggestive of infection in the urinary tract. Start with you primary care provider, however, you may need to consult a nephrologist or urologist depending in initial findings. Wish you good health!
