- A small, unbroken blister about the size of a pea, even a blood blister, will usually heal on its own. Use a loose bandage to protect it. Avoid the activity that caused the blister.
- If a small blister is on a weight-bearing area like the bottom of the foot, protect it with a doughnut-shaped moleskin pad . Leave the area over the blister open.
- It's best not to drain a blister at home. But when blisters are painful, some people do drain them. If you do decide to drain your blister, be sure to follow these steps:
- Wipe a needle with rubbing alcohol.
- Gently puncture the edge of the blister.
- Press the fluid in the blister toward the hole so it can drain out.
- Do not drain a blister of any size if:
- If a blister has torn open, or after you have drained a blister:
- Gently wash the area with clean water. Don't use hydrogen peroxide or alcohol, which can slow healing.
- Don't remove the flap of skin over a blister unless it's very dirty or torn or there is pus under it. Gently smooth the flap over the tender skin.
- You may cover the blister with a thin layer of petroleum jelly, such as Vaseline, and a nonstick bandage.
- Apply more petroleum jelly and replace the bandage as needed.
Watch for a skin infection while your blister is healing. Signs of infection include:
- Increased pain, swelling, redness, or warmth around the blister.
- Red streaks extending away from the blister.
- Drainage of pus from the blister.
Home remedies may relieve itching from blisters. One way to help decrease itching is to keep the itchy area cool and wet. Apply a cloth that has been soaked in ice water, or get in a cool tub or shower.
