Be careful! Remember to go to the drugstore to buy anti-inflammatory drugs, and don't wrap gauze too thick in summer. Of course, the gauze should not be wet. Wet gauze is used to clean the wound. If there is blood residue in the wound, you'd better go to the hospital. If only it was an itch. Itching means that the wound is growing meat. This is a normal phenomenon. Just bear with it, but if it itches and the wound is red, remember to go to the hospital at once.
