Heel grinding out blisters (blisters) is mainly caused by wearing unsuitable shoes or walking for too long, etc. There is no fastest treatment, mainly symptomatic treatment, which can be treated according to the size of the blisters. If the diameter of the blister is less than 1cm, no special treatment is needed and it can be absorbed by itself. If the diameter of the blister is larger than 1cm, it can be disinfected with iodine volts and other disinfectant, and then the blister can be punctured with a sterile needle to discharge the liquid, and appropriately bandaged. Disinfection and dressing change should be done regularly every day to avoid infection.
