Bacterial prostatitis is an infection of the prostate gland, which can cause inflammation and discomfort. It is often caused by bacteria that enter the prostate through the urethra. Symptoms may include pain in the lower abdomen, difficulty urinating, and flu-like symptoms such as fever and chills. This condition can be acute, developing suddenly, or chronic, persisting over time. Diagnosis typically involves a physical examination, urine tests, and sometimes imaging studies. Treatment usually includes antibiotics to eliminate the infection and may also involve pain relief measures to manage symptoms.
