Hello for those who have bacterial prostatitis, I am just wondering how long it takes for it to heal - In other word, how long the prostate will shrink back to normal size?

It is hard for me to make an appt to see a doc, so I went to see a PA-C, who did the DRE and said mine is a little tender. She had me done the urine sample and cultured then the bacteria Enterococcus faecalis is found, she then prescribed me the ampillicin for two weeks. Then no antibiotic for another two weeks. Then she had me done urine culture again, this time the bacteria is serratia marcescens, what she prescribed me this time is bactrim for 28 days. I have been taking it for 3 days but does not have any improvement. Will this help and cure the prostatitis?

Right now urinating is extremely difficult for me (obstruction in the bladder). When I go, I have to strain it and it takes up 1 min to initiate the stream and then little comes out - mostly dribbling. The moment I finish, a min later, I have to go again.

I am just wondering if the urine culture is enough to determine the bacteria that causes prostatitis? Will it be possible that she could have misdiagnosed? Thanks.
