How long does it take for a blood blister to heal on its own?

Blood blisters should be left alone so they can heal. Blood blisters and friction blisters usually heal after one or two weeks. They heal because new skin forms below the blister's raised layer. Over a period of days or weeks, the liquid in the blister will dry out.

How do you treat a blood blister?

DO Elevate and Ice Your Blister. Once you get a blood blister, elevate the injury to reduce swelling and minimize its size. If your blood blister hurts, especially if it was a result of pinching, use an ice bag wrapped in a towel or a cold compress.
