What is the cause of frequent and burning urination with swollen penis?

Hello doctor,

I am frequently urinating, and it is burning afterward and after sex. It got better for a week, and I had left flank pain for a day. I have burning in my back, stomach, and penis. The penis feels swollen a little. This problem started a month back and came and went. I drank alkaline water (honey and lemon) yesterday and went to a urologist last week. He prescribed Doxycycline for ten days and was better until the end of the week, and now no results. Previously, I was diagnosed with prostatitis 20 years ago, and I had the problem of frequent urination also. Prostatitis starts if I drink certain beverages, last for hours, and go away. Currently, I am taking Nifedipine, Lipitor (Atorvastatin), Potassium, Baby aspirin (Aspirin), and Ciprofloxacin only when needed. Nifedipine causes me to wake two to three times at night, and I am used to it. I have discontinued Bystolic (Nebivolol) due to burning urine for two years. I have performed multiple lab tests, and mycoplasma was performed. PSA was good with negative results when I took it two months ago.
