How to know if i have another prostate infection, where urine culture was negative?

Here are some ...: The real bacterial infection in the prostate is not common although many men have been told they have prostatitis.In fact, more than 80% of prostatitis is non-bacterial. With these in mind, you would be more able to ask and talk with Doc in a more sensible way so to deduce more reasonable Rx / care.
