Recurrent cystitis in men often signals underlying issues (BPH, chronic prostatitis, immunity). Korean medicine treatment: ① clear damp-heat (Paljungs-an, O-ryeong-san), ② strengthen kidney/spleen Qi (constitution-based prescription), ③ acupuncture, ④ pharmacopuncture for chronic cases. Antibiotics combined reduce recurrence by 60–70% over 3–6 months. Lifestyle (water intake, hygiene, immunity boost) is also crucial. Investigate underlying causes if recurrence is frequent.
