Infection continues to be the most common cause of the symptoms. I agree with the antibiotic choice thus far.
Further evaluation of the prostate can also be considered, in the form of a prostatic massage or a transrectal ultrasound. If prostatitis continues to be suspected, sometimes it may requires several weeks to months of antibiotics. If an abscess is present, it would need to be drained.
If infection has been ruled out, anatomical or structural causes like a urethral stricture or polyp can be considered.
These options can be discussed with your personal physician, or in conjunction with a urologist.
Followup with your personal physician is essential.
