Diagnosed with a prostate infection how long till symptoms go away?

The symptoms will pretty much be gone in 10 days to two weeks but the infection won't be cleared up for about a month. Some urologists have told me the infection never completely goes away in the prostate gland. Supposedly it's similar to a sponge and the bacteria can hide in the cracks so to speak. I'm inclined to believe that because I've had chronic prostatitis over the years.
