Blisters do not necessarily need to be picked, and for particularly large blisters that are accompanied by pain and swelling, the fluid inside can be released to relieve the swelling. Smaller blisters with no conscious symptoms don’t need to be punctured, they can dry up and absorb on their own, and then crust over and fall off. If the blisters are large and need to be broken, it is necessary to use sterile syringe needles or sterile scissors after local disinfection to release the blisters at the base of the blisters, and the blisters need to be disinfected again after the blisters are completely cleared, and then a pressure bandage is applied, otherwise the blisters will soon reappear, and it is necessary to repeatedly release the blisters, and it is necessary to pay attention to the emergence of blisters to avoid friction as much as possible. After the blister rupture, we should also pay attention to retain the wall of the blister, the wall of the blister can protect the wound.
