I can understand your feelings, and I was depressed at that time, but the doctor clearly told me that every time I fiddled with the wound, bacteria might invade, which led to the slow healing of the wound, so I changed the medicine at most once a day. At that time, I only rubbed iodophor, then dried it with a hair dryer and wrapped it with sterile gauze. Remember to go to the hospital to buy sterile gauze for packaging bags. Psychologically speaking, wound healing needs a process.
