If the blisters are small, you can wait for them to absorb on their own. If the blisters are large, you can pick the blisters and disinfect the area to prevent infection. Most of the blisters are caused by wearing ill-fitting shoes when playing sports, and the friction damage leads to abnormal accumulation of tissue fluid between the epidermis and the dermis layer of the skin and become blisters. If the blisters are relatively small, you can not pick the blisters, reduce exercise, so as not to make the local skin friction aggravate the tissue fluid exudation, and wait for the blisters to absorb themselves. If the blisters are bigger, you can go to the hospital to pick the blisters with the help of the doctor, and use iodophor and other disinfectants to disinfect the local area, and cover them with sterile dressings, disinfect them regularly, and change the medication. If the feet are abraded with blisters, please follow the doctor’s instructions for treatment.
