Hello Doctor, I am a 30-year-old male. I had recurrent urinary bacterial infections in the past and took multiple antibiotics. After treatment, urine culture now shows no growth. Earlier, after prostate massage, bacteria were found, but after antibiotics, culture became normal again. Currently, urine routine and culture are normal, but I still have burning after urination. This has been ongoing for about 3 years. Other symptoms/history: - Itching at the tip of the penis after urination - Daily masturbation - Atomoxetine caused urine retention - Contrast CT was normal, but contrast also caused urine retention - Had to strain to pass urine Questions: 1. What could be causing burning after urination despite normal tests? 2. I need Atomoxetine to function. Can I restart it? Will urine retention happen again? What should I do if it does? Thank you.
