Chronic prostatitis is an inflammatory condition that occurs in the prostate gland, which is not contagious but has long-lasting and treatment-resistant symptoms. To be diagnosed with chronic prostatitis, symptoms must be present for at least three months. In acute prostatitis, the symptoms pass much more quickly. Chronic prostatitis typically causes pain in the lower pelvis area of men. Urinary tract symptoms such as frequent urination and burning during urination may also be present.
