I had prostatitis (bacterial infection). i took full antibiotic course. i want to know how does prostatitis recur? and what i need to do to stop it?

Difficult to treat: Prostatitis is difficult to treat as it usually takes 3 to 4 weeks of antibiotics to clear. As a 27 year old it is not a common issue either. It is typically bacterial infection. YOu may have a swollen prostate from something else too, like prolonged sitting or bike riding.

Yes: often recurs. Sometimes it depends on your anatomy and you cannot prevent it. Also difficult to treat, need the right antibiotic for the right amount of time or it will seem like a new infection in fact may be the same one again. Prevention: single partner, increase fluids, address issues of prostate enlargement if they occur. Notify your doctor if any changes to your urinary stream
