Blisters are fluid-filled blisters on the skin when rubbed. You can get blisters on your feet from shoes that are too tight or on your hands after a day of hoeing in the garden. When you have a blister, you need to know how to care for it at home to help it heal faster and prevent infection. However, sometimes you need medical treatment when the blisters are large or infected.
Steps
Treat small blisters at home
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8d/Treat-a-Blister-Step-1-Version-2.jpg/v4-460px-Treat-a-Blister- Step-1-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8d/Treat-a-Blister-Step-1-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-1-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Wash the blistered area with soap and water. When blisters appear, big or small, it’s important to keep them clean. This will prevent the blister from becoming infected if it accidentally breaks.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3b/Treat-a-Blister-Step-2.jpg/v4-460px-Treat-a-Blister-Step-2. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3b/Treat-a-Blister-Step-2.jpg/v4-728px-Treat-a-Blister-Step- 2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Keep the blisters breathable. The blisters are small and do not break open on their own within a few days. You don’t need to puncture or bandage, just let the blister air out as much as possible. [1] X Trusted Source Mayo Clinic Go to Source
- If the blister is on your foot, wear sandals or slippers at home to give it time to heal.
- If the blister is on your hand, you don’t need to wear gloves or an armband as you’re not doing anything that could cause it to break or become infected.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d4/Treat-a-Blister-Step-3-Version-2.jpg/v4-460px-Treat-a-Blister- Step-3-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d4/Treat-a-Blister-Step-3-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-3-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Protect unbroken blisters. When leaving the house or participating in an activity, protect the blister so it does not burst. You can either use a loose bandage or use mpeskin tape with a hole in the center of the donut shape to protect the blister. [2] X Trusted Source American Academy of Dermatpogy Go to Source
- Donut-shaped mpeskin tape is available at most drugstores. This product creates a protective barrier around it while keeping the blisters breathable.
Treat large blisters at home
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/81/Treat-a-Blister-Step-4-Version-2.jpg/v4-460px-Treat-a-Blister- Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/81/Treat-a-Blister-Step-4-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Gently wash the blistered area. Wash the blister and surrounding skin with warm soapy water. Make sure your hands are clean too, as blisters are often prone to infection. [3] X Trusted Source Mayo Clinic Go to Source
- Remember to be gentle when washing the blister. Try to keep the blister intact before you can properly puncture it.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3d/Treat-a-Blister-Step-5.jpg/v4-460px-Treat-a-Blister-Step-5. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3d/Treat-a-Blister-Step-5.jpg/v4-728px-Treat-a-Blister-Step- 5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Drain the fluid in the blister if it ruptures. Press the blister with your finger. You should see fluid begin to drain through the opening. Continue pressing until the fluid drains out, then wipe it off with a cotton ball.
- Hygiene drainage can help wounds heal faster and reduce pain from swelling.
- If the blister doesn’t break on its own, you should see a doctor to get it treated.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/57/Treat-a-Blister-Step-6-Version-2.jpg/v4-460px-Treat-a-Blister- Step-6-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/57/Treat-a-Blister-Step-6-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-6-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Do not peel off the skin above the blister. A blister that has drained away will leave a piece of skin. This piece of skin will protect the underlying skin from infection, and you don’t need to peel or cut it.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/30/Treat-a-Blister-Step-7-Version-2.jpg/v4-460px-Treat-a-Blister- Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/30/Treat-a-Blister-Step-7-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-7-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Apply ointment to the blister after draining the fluid. Use a cotton ball to apply ppymyxin B or bacitracin antibiotic ointment to the wound. This step will prevent infection and keep the bandage from sticking to the skin. [4] X Trusted Source Mayo Clinic Go to Source
- Some people are allergic to antibiotic ointments. If you are allergic, you can use petroleum jelly (Vaseline cream) instead of antibiotic ointment.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/bd/Treat-a-Blister-Step-8-Version-2.jpg/v4-460px-Treat-a-Blister- Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/bd/Treat-a-Blister-Step-8-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Bandage broken blisters. You need to protect the blister so it doesn’t get infected. Use a bandage or gauze to lightly cover the wound. Make sure the tape does not touch the blister. [5] X Trusted Source American Academy of Dermatpogy Go to Source
- Change the dressing once a day, or every time it gets wet or dirty.
- If the blister is on your foot, you should wear socks and choose shoes that feel comfortable. Don’t cause further irritation by walking back and forth in the shoes that gave you the blisters in the first place.
- If the blister is on your hand, you need to wear gloves when doing daily household chores like washing dishes or cooking. Do not repeat the work that caused the blisters on your hands.
Seek medical attention
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/bc/Treat-a-Blister-Step-9-Version-2.jpg/v4-460px-Treat-a-Blister- Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/bc/Treat-a-Blister-Step-9-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Consider seeing a doctor for large blisters. Blisters that are large, painful, and in hard-to-reach places may require medical attention. The doctor has sterile instruments to drain the fluid. This ensures cleaning and disinfecting of the wound before you leave the clinic.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b8/Treat-a-Blister-Step-10-Version-2.jpg/v4-460px-Treat-a-Blister- Step-10-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b8/Treat-a-Blister-Step-10-Version-2.jpg/ v4-728px-Treat-a-Blister-Step-10-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
See your doctor if the blister becomes infected. Infected blisters have the potential to lead to more serious problems, so it’s best to see a doctor to get them checked and given proper treatment. Your doctor may wash the wound and bandage it, and then prescribe antibiotics for you. Signs of infection include: [6] X Trusted Source American Academy of Dermatpogy Go to source
- Redness, itching, swelling around the blister.
- Yellow pus appears under the skin on the blister that has collapsed.
- The skin around the blister feels warm to the touch.
- Red streaks emanating from the wound.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c2/Treat-a-Blister-Step-11.jpg/v4-460px-Treat-a-Blister-Step-11. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c2/Treat-a-Blister-Step-11.jpg/v4-728px-Treat-a-Blister-Step- 11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Seek emergency medical attention if severe symptoms develop. In rare cases, an infected blister can lead to bigger problems as the infection spreads throughout the body. You need emergency medical attention if you have the following symptoms:
- High fever
- Chills
- Vomit
- Diarrhea
Blister prevention
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f5/Treat-a-Blister-Step-12.jpg/v4-460px-Treat-a-Blister-Step-12. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f5/Treat-a-Blister-Step-12.jpg/v4-728px-Treat-a-Blister-Step- 12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Wear gloves when working with your hands. Blisters form mainly due to repetitive movements that cause friction. If you put on gloves before working, you will reduce friction and can prevent blisters from appearing. [7] X Trusted Source American Academy of Dermatpogy Go to Source
- For example, when you use the shovel for a long time, the shovel handle will be rubbed repeatedly at the same place. However, the gloves that you wear when using the shovel will form a cushion for your hands and prevent blistering.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5f/Treat-a-Blister-Step-13.jpg/v4-460px-Treat-a-Blister-Step-13. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5f/Treat-a-Blister-Step-13.jpg/v4-728px-Treat-a-Blister-Step- 13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Wear suitable footwear. New or ill-fitting shoes can cause blisters, especially on the toes and heels. To avoid blisters on your feet, you need to make sure you choose the right shoes. Stretch out new shoes by wearing them often, but only for short periods of time. This will help the new shoes stretch out without the foot being rubbed too long enough to blister.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f4/Treat-a-Blister-Step-14.jpg/v4-460px-Treat-a-Blister-Step-14. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f4/Treat-a-Blister-Step-14.jpg/v4-728px-Treat-a-Blister-Step- 14.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Protect areas of skin that will be subjected to constant rubbing. If you know in advance that your shoes will cause blisters on your feet, or if you’re going to participate in an activity that could blister your hands, you should be proactive about protecting yourself. Wedge pads to areas of skin that will be rubbed to prevent blisters from forming. [9] X Trusted Source American Academy of Dermatpogy Go to Source
- For example, you can tape a spot on your hand that gets rubbed when doing a craft project or when performing repetitive movements.
- If your feet are often blistered, you should wear 2 pairs of socks to create extra cushioning for your feet.
- In pharmacies, there are pads designed to cushion the areas of the foot that often rub against shoes. These pads are called “mpeskin” patches, which are usually glued to the skin to keep them in place.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b6/Treat-a-Blister-Step-15.jpg/v4-460px-Treat-a-Blister-Step-15. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b6/Treat-a-Blister-Step-15.jpg/v4-728px-Treat-a-Blister-Step- 15.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Reduce friction between skin surfaces. Use lotion, baby powder, or wax to reduce friction between the two surfaces of your skin. For example, if your thighs are constantly rubbing against each other, you should apply Vaseline cream to the area where the skin is rubbed so as not to create friction and heat that can blister the skin. [10] X Trusted Source American Academy of Dermatpogy Go to Source
- For example, long-distance cyclists often experience rubbing their skin, which leads to blisters. Lubricants applied between areas of skin that have been rubbed can help reduce discomfort and limit blistering.
