Prostate Problem : Is it possible that prostate again occurs after surgery of 3-4Months?

In Novermber-2016, my father had surgery of the prostate, he is comfortable for 2-3Months but now again the same pain and problem he is feeling same as before surgery. So is this possible the prostate again occurs?

could be an infection.  What surgery anyway? Your question has no answer without that info

You do not say what kind of surgery your father had on the prostate.  May be the proplam was not the prostate it could have been the bladder or the kidneys.  The prostate does continiue to grows has a men gets older but not that fast  Ken 

I also had Prostate op more than 10 years back. It remained the same as after op for a long time. even now after so long it is increased but not too much.
