how long does it take for a blood blister to heal
A blood blister should not be popped. The captured blood acts as a cushion to prevent further damage to the finger. The numbness may be due to the crush of very fine nerve endings on the tips of the finger.eport Abuse. Well you were right it will take 2-3 week to heal. I popped mine and blood came shooting out so I advise that you not pop it. It will dry up on its own.
