Quick Scoop

A blood blister usually heals on its own, so the main goal is to protect it , keep it clean, and avoid popping it. Most sources recommend washing gently with mild soap and water, covering it with a bandage, and using ice or an over-the-counter pain reliever if it hurts.

What to do

  1. Leave the skin intact. Don’t poke, squeeze, or peel it. Keeping the skin roof in place lowers the chance of infection.
  1. Wash gently. Clean the area with mild soap and water, then pat it dry.
  1. Cover it. Use a clean bandage or gauze to protect it from friction and dirt; change it daily if needed.
  1. Reduce pain. A wrapped ice pack can help, and acetaminophen or ibuprofen may ease discomfort if you can take them safely.

If it pops

If the blister opens on its own, rinse it with clean water, do not tear off the loose skin, and re-cover it with a clean dressing. Keeping it protected while the new skin forms helps it heal more smoothly.

When to get help

Get medical care if it is very painful, keeps coming back, looks infected, is near the mouth or eyes, or you have trouble walking or using the area normally. Also get checked sooner if you have diabetes, poor circulation, or a weakened immune system, since even small skin wounds can become more serious.

Simple rule of thumb

Think “clean, cover, don’t pop.” That is the safest default for most blood blisters.
