1 Keep the epidermis at the top of the blister, and pump out the liquid with sterile empty needle to reconnect the top and bottom of the blister, which not only minimizes the pain, but also prevents bacterial infection.

2. Protection of blisters: Once the top and bottom of blisters are attached, the pain will disappear, but before the epidermis is completely regenerated, the best way is to cover the blisters with a small gauze, and then attach them with a special soft leather pad or a thick gauze or cotton pad, as long as the blisters are not broken when replacing.

3. Prevention of bacterial infection: Applying anti-infective drugs on the surface of broken blisters and sticking them with small gauze or adhesive tape can also prevent bacterial infection.
