I've also been treated at Onyu Hang Surgery in the past. It's a renowned hospital not only for anal diseases but also for cyst removal. When I went there for anal itching, they advised me that a sitz bath was the only way to survive, and when I had a sebaceous cyst removed, they confirmed it through thorough consultation and examination. The results were successful, and I've been living without any discomfort since. This time, I visited the hospital because I wasn't sure if it was acne or a sebaceous cyst on the back of my head. They told me it was folliculitis, but it was so mild that no prescription was needed. They always put their patients first, and even though I'm often anxious about my health, they always provide kind explanations.
