Foot blisters can occur due to friction between your feet and shoes. This is usually the result of excess moisture on the skin. Blisters are usually not serious and can be treated at home with antibiotic creams and bandages. Note that it is usually best to let a blister heal on its own, but very painful blisters can be popped with the right tools and proper sanitary practices.
Steps
-
Cover your blister. Foot blisters should be covered to reduce irritation and cut back on the risk of infection. Cover your blister with a soft dressing, like gauze or a loose bandage. If the blister is very sore, cut your dressing into a donut shape and place it around the blister to avoid putting pressure directly on it.

- If your blister is just a superficial irritation on your skin, you may only need to cover it with a bandage and leave it alone. It should dry out and be fine after a couple of days. [2] X Research source Catherine Cheung, DPM. Podiatrist. Personal interview. 12 May 2020.
- Your dressing should be changed each day. Always wash your hands before touching the dressing and the area around the blister.
-
Use antibiotic ointment or petroleum jelly. Antibiotic ointment helps prevent infections in a blister. You can buy antibiotic ointment at a pharmacy. Apply it to the blister as directed, especially before you put on your shoes or socks. Just petroleum jelly may also be used.

Try powders and creams to reduce friction. Friction can make a blister worse and increase pain. In order to reduce friction on a foot blister, pick up a powder designed for your feet at a local pharmacy. Pour it into your socks before putting on your shoes to reduce pain. [4] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source
- Not all powders work for everyone. If a powder causes your blister to become irritated, stop using it.
-
Care for your feet while the blister persists. Take extra precautions to keep your feet comfortable while a blister is healing. Wear an extra pair of socks and loose-fitting shoes as the blister persists. More padding can help you feel more comfortable when you're walking, which may help the blister heal more quickly. [5] X Research source Catherine Cheung, DPM. Podiatrist. Personal interview. 12 May 2020.
- You should also try to stay off your feet as much as possible while the blister is healing.
- Try changing your socks twice a day to help decrease the possibility of blisters, usually cotton socks are better than polyester.
-
Protect a burst blister from infection. Unless a blister becomes extremely painful, it's best not to drain it yourself. This can increase your likelihood of developing an infection. Let the blister's skin peel on its own. Avoid touching or irritating the blister to prevent it from popping prematurely.

- Use a moleskin over the blister to protect it if you must walk on it.

-
Wash your hands. In rare cases, you can pop an extremely sore blister on your own. You should only do this if the pain becomes debilitating. Before popping a blister, wash your hands thoroughly with antibacterial soap and water. You should never touch a blister with dirty hands. [7] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source
- Only drain a blister if it's a large area that's filled with fluid. If it's small or minor, let it heal on its own.
-
Clean the blister. Before popping your blister, clean the area around it with water. Using alcohol, hydrogen peroxide or iodine can slow healing.
-
Sterilize the needle. You will use a sewing needle to pop the blister, but this should be sterilized first to prevent infection. Wipe the needle down with rubbing alcohol, which you can purchase at a local drugstore. [8] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source You can dab rubbing alcohol from a bottle onto a cotton swab or use rubbing alcohol pads.
- Alternatively you can sterilize the needle by running it through an open flame until it turns red. Use something to grasp the needle when you do this like Kelly clamps, since the needle will become very hot.
-
Puncture the blister. Take the needle and gently insert it into the blister. Puncture it several times, near the edge of the blister. Allow the fluid to drain out naturally while you leave the skin covering the blister in place. [9] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source
- Do not remove the skin from the top of the blister. Just drain the fluid, then cover the blister with a bandage. That piece of skin will eventually dry up and fall off on its own. [10] X Research source Catherine Cheung, DPM. Podiatrist. Personal interview. 12 May 2020.
-
Apply an ointment. Once you've drained the blister, apply an ointment to it. You can use Vaseline or Plastibase, both of which can be purchased at a drugstore. Use a clean cotton swab to rub the ointment over the blister. [11] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source
- Some ointments may irritate a blister. If you notice any signs of a rash, cease use of your ointment.
-
Cover the blister. Place a piece of gauze or a bandage over the blister. This will protect it from infection while it heals. Change the dressing twice a day and, when you change it, add new ointment.

See a doctor if you notice complications. Most blisters heal on their own. However, complications warrant a trip to the doctor. If you notice any of the following complications, make an appointment with your doctor: [13] X Trustworthy Source National Health Service (UK) Public healthcare system of the UK Go to source
- A painful, red, and hot blister or a blister with red streaks
- Yellow or green pus
- A blister that keeps coming back
- Fever
- Having diabetes, heart conditions, auto immune disorders, HIV or undergoing chemotherapy can make your blister rapidly become worse, causing sepsis or cellulitis.
-
Rule out underlying conditions. Most foot blisters are benign. However, some blisters can be caused by underlying conditions like chicken pox and should be treated differently. Depending on your other symptoms, your doctor may want to run some tests to rule out underlying conditions before addressing your blister. If an underlying condition causes your blister, your doctor will advise you how to treat it. [14] X Trustworthy Source National Health Service (UK) Public healthcare system of the UK Go to source
-
Follow your doctor's treatment plan. Depending on the cause of the blister, your doctor will form a treatment plan for you. Follow all of your doctor's instructions closely and ask your doctor any questions you have before leaving the office.

-
Avoid wearing the shoes that caused a blister. If your blister came in response to a new type of shoe, or a very uncomfortable shoe, stop wearing the shoes that caused it. Purchase shoes that leave your feet with some wiggle room and fit comfortably. Wearing the right shoes can prevent a future blister.
- Also make sure that you wear the right type of shoes for the activity you're engaging in. For example, you can help prevent foot blisters when running by wearing running shoes.
- Try to figure out exactly what's causing the abnormal motion that's causing your blister. For instance, it could come from a fold in your sock, or from an ill-fitting shoe. [16] X Research source Catherine Cheung, DPM. Podiatrist. Personal interview. 12 May 2020.
-
Add moleskin or padding to your shoes. Attach a small bit of moleskin or padding to the inside of your shoes, particularly the sole, or the areas where your shoes rub against your feet. Moleskin can provide some padding and cut back on friction and irritation that causes blisters. [17] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source
-
Wear moisture-wicking socks. Moisture can cause blisters or make existing blisters worse. Invest in a pair of moisture-wicking socks. These will absorb sweat from your feet and cut back on blisters and other injuries. [18] X Trustworthy Source Mayo Clinic Educational website from one of the world's leading hospitals Go to source

- Don't walk on it for a while - it still will be sore as its healing, so if you do decide to get back to sports, make sure that it is fully healed. If it isn't painful, but still there, don't carry on with your sports! You'll end up hurting yourself, and probably get another blister.Thanks
