Blisters are blisters. Hand rubbed blisters, if it is smaller blisters, do not need special treatment, larger blisters need puncture, sterilization bandage. 1. Smaller blisters: If the blisters are smaller, generally pay attention to rest, avoid rubbing again, most will be absorbed by themselves, do not need special treatment. 2. Larger blisters: If the blisters are larger with more exudate, you can use iodine to sterilize the blisters and the surrounding skin, then use a sterile needle to puncture the bottom of the blisters to discharge the exudate, and then disinfect them again with iodine and bandage them with sterile gauze to prevent infection. Hand grinding blisters, if you need to puncture treatment, you need to go to the regular hospital to find a professional doctor for puncture bandage, avoid puncturing the blisters yourself, so as not to induce infection.
