My finger !!! Help ME?

DO NOT POP IT! That blister is acting as a natural bandage, and preventing infection. Keep a bandage over it, and let it pop on it's own. After it pops, wash it out with soap and water, and cover it with a sterile band aid while it heals. Make sure you keep it clean and dry after it pops. You may put some Neo-sporin or Polysporin on it sparingly.
