Pain is one of the common symptoms of prostatitis. The pain of prostatitis includes painful urination caused by dysuria, perineal and suprapubic pain accompanied by external genital discomfort or pain. Acute bacterial prostatitis is mostly caused by upstream infection of the urethra, such as transurethral instrumentation. The causative organisms are mostly gram-negative bacilli or pseudomonas, most commonly Escherichia coli. Acute bacterial prostatitis usually has a sudden onset and often presents with acute pain, urinary irritation, obstruction, fever and systemic symptoms. General treatment includes active bed rest, infusion of fluids, and application of antimicrobial drugs. If the diagnosis of prostatitis is confirmed, you should consult a doctor in time, under the guidance of the doctor, and follow the doctor’s instructions to standardize the treatment.
