Been having problems with prostatitis for many years and have tried everything.
You need at LEAST a one month course of antibiotics for prostate infections. When you find the right one, you'll know in about 10 days, then stay on it at least another 3 weeks.
I only respond to bactrim anymore. Quinolones have no effect. Has to be at least 30 days or it will come right back and all you do is wipe out the weak organisms and culture the resistant ones.
The urine will likely be clean, as will the prostatic fluid, nothing will culture, but you'll still have an infection. May even be non-bacterial inflammation in which case I'd be loading on fish oil and lycopene.
I suggest Flomax, one cap a day. No sides except slightly lower BP which in my case is good as I'm borderline hypertensive. No effects on exercise intensity. Relieves prostate congestion and reduces the incidence of infection. ECA makes it worse because it causes constriction as does stress.
You can add in Avodart with the flomax and antibiotic. This will really shrink the prostate. Avodart for only about 6 weeks. It may lower your libido and drive somewhat.
Probiotics may also be helpful. Some are finding that abnormal gut flora contributes to prostatitis. No one knows why yet, but that is the thinking.
