How to Heal Blood Blisters

Ouch! You managed to pinch your finger in the door and now you notice a blistering of the skin that’s filled with blood instead of pus. You’ve developed a blood blister, a type of blister that forms when an area of the body has been pinched or traumatized, causing a pooling of lymph and blood to be trapped under the skin.

Hands and feet are the most common places for blood blisters to occur on the body, usually as a result of some mechanism, tool or weight pinching the skin. To prevent infection, there are a number of steps to take in helping heal a blood blister.

Avoid Breaking

As tempting as it may be to pop the blister, this action can bring infection, so the best course of action immediately is to leave the blister alone and protect it using some moleskin. If the blister breaks unexpectely, flush out the area, apply an antiseptic ointment and cover with a clean bandage which is changed daily. If left alone and unbroken, a blood blister usually dries up and heals within a few days.

Ice Packs

Applying an ice pack will help reduce the inflammation around the blood blister and lessen the accompanying pain.

Epsom Salt Soak

Dissolve Epsom salts in warm water and soak the blood blister in this solution prior to applying a clean bandage which should be changed daily.

Drain Properly

If you must use the hand or foot where the blood blister occurs and are afraid of it breaking unexpectedly, you can carefully drain the blister. Disinfect a sewing needle and prick the skin at the bottom of the blood blister to allow it to drain down the side, leaving the skin on the top of the blister intact. This method causes the least amount of disruption to the skin and allows the blister to heal properly. Apply an antiseptic spray or ointment to protect against infection and cover the blood blister with a band-aid or other bandage which should be changed daily until the blood blister is fully healed. Another good drainage method is to pull a thin disinfected cotton thread through the blister from the side, so that the fluid will seep out slowly, again leaving the skin on top intact as a preventative measure against infection.

Blood blisters can be painful, but should be left alone for fastest healing, using ice packs and Epsom salt soaks for pain relief. If a blister breaks or must be broken, antiseptic application and a daily clean bandage will help avoid infection while the blood blister heals.
