Thank you for your query at DoctorSpring.com
You have typical symptoms suggestive of chronic prostatitis. For exact diagnosis a digital rectal examination needs to be done, and prostatic secretions need to be cultured. You need antibiotics as well as an alpha blocker as of now.
You can take doxycycline 100 mg twice daily for 4 weeks and c. Tamsulosin 0.4 mg once daily for 6 weeks.
Feel free to discuss further,
