Prostatitis Prostatitis occurs when the prostate becomes infected and it can happen at any time in a man's life. The main symptoms are repeated bladder infections and it's considered to be chronic prostatitis or chronic pelvic pain syndrome (CPPS) if the symptoms do not clear after three months. Occasionally, prostatitis is due to a bacterial infection although this only accounts for around 10 percent of cases. Symptoms include fever, pain and burning when urinating, lower back pain and groin pain, painful ejaculation and an increased frequency of urination. Antibiotics are used to treat bacterial prostatitis and chronic prostatitis is treated with medication, lifestyle changes and in severe cases, surgery. Five prostate cancer symptoms to be aware of.
