Boil surgery at Bucheon Woobang Surgical Clinic, an unexpected treatment method

I developed a boil on my chest... At first, I didn't realize it was a boil and thought it was acne, so I slept at home... but the area got bigger, and it started to get hot and spread... I tried taking anti-inflammatory medicine and buying bandages from the pharmacy, but they didn't work... I went to a local internal medicine clinic, but they told me I needed to go to a surgical department for surgery... so I came back and started looking for a surgical clinic again... The hospital was a bit run-down, or perhaps a bit old... There was an elderly doctor there, and he immediately administered anesthesia and made an incision about 5 centimeters long... I thought they would suture it, but they said the wound had to be left open like this, so I came back just like that.
