Hello,
Thank you for your query at DoctorSpring.com
It is quite possible that you are having prostate infection.
Prostate infection typically has waxing and waning pattern and patient experiences symptoms at intervals with no symptoms for days to weeks.
You should take antibiotics for 3 weeks and see how you do. I feel you will get better once you complete a full course of antibiotics.
Feel free to discuss further,
Take care
Sincerely
Rajiv Goel
