What do you mean by:
but doctor think I have Chlamydia inside the prostate

It is too simple tests that diagnose Chlamydia, without saying - i think you have chlamydia ...
Dont think now about kind of "therapy" - you must do tests to find out if you still have a chlamydia because it is very very bad thing.
Prostatitis symptoms continue - it may be even you already dont have chlamydia .
So, make the test and report here after it ( if you wish )
