“If the blister is very large, hurting, or infected then please see a professional. They may pop the blister and dress the area accordingly. They will keep the top layer of the skin intact, as the skin protects the blistered area. If you do not have any issue with the blister then it is recommended to leave it alone as the blister will get better by itself and the fluid will return back to the body and the skin will become flat. Popping it may increase the risk of infection in the area,” says Marion.
Ideally, you should leave the scab alone, cover it with a plaster and let it heal naturally. Painkillers can be used if the area is sore. Regularly changing your plaster and checking the area can help you catch any infections early. If you suspect an infection, talk to a healthcare professional.
