How to treat a blister burn 
Run cool water over the blister. 
The first thing you can do to treat a blister burn is to run cool or lukewarm water over the affected area. You can also use a cool bath or press a towel soaked in cool water on the burn.

Possible answers: -- This will help move the sting further and reduce the swelling. You can submerge a towel in cool water and gently rub the burn area until it has cooled.; -- Allow the area to cool down for at least 20 minutes so you can remove the bandage. You may want to untape the bandage to ensure you do not pull the needle out while you are running water over it.; -- Keep the affected area in the cool water for 10 to 15 minutes. Make sure you are using cool water and not cold or ice water.; -- You can also cool your skin by soaking the affected area in cold water (however, if it is cold, the ice will offer the most relief). Use a heat pack on the burn.;
