How to Treat Foot Blisters

Blisters on the feet can form due to friction from shoes or excessively moist skin. In most cases, foot blisters are not serious and can be treated at home with antibiotic creams and bandages. Although it is best to let the blisters heal on their own, severe blisters may need to be drained with the appropriate tools and properly cleaned.

Cover the blisters with a bandage. Foot blisters need to be covered to reduce friction and prevent infection. You can cover the wound with soft gauze or a liquid bandage. If the blister is too painful, you can cut a hole in the middle of the gauze, like a donut, to avoid putting pressure directly on the wound.

• If the blister is just an irritated area of skin, you can simply bandage it and leave it to heal on its own. It will dry up and heal in a few days.
• You should change the bandage daily. Always wash your hands before touching the bandage or the skin around the blister.

Apply antibiotic ointment or petroleum jelly (Vaseline). Antibiotic ointments can help prevent infection. You can purchase an antibiotic ointment at a pharmacy and apply it to the blister as instructed, especially before wearing shoes or socks. Alternatively, you can use petroleum jelly in place of the ointment.

• Be sure to wash your hands thoroughly before touching the blister.

Try using powder and cream to reduce friction. Friction can worsen the blister and make it more painful. To reduce friction on the blister, visit a pharmacy to find foot powder designed for this purpose. Sprinkle the powder on your socks before wearing shoes to ease discomfort.

• Not all powders are suitable for everyone. If you experience irritation from a particular powder, stop using it immediately.

Take care of your feet while the blister is healing. It's important to care for your feet while the blisters are healing. Wear an additional pair of socks and choose loose shoes until the blisters are fully healed. Extra cushioning can make walking more comfortable and may help the wound heal faster.

• Avoid touching your feet while the wound is still healing.
• Try changing your socks twice a day to reduce the risk of developing blisters. Cotton socks are generally better than polyester socks.

Protect a burst blister from infection. Unless the blister is extremely painful, it's best not to attempt draining it yourself, as this could increase the risk of infection. Let the top layer of skin peel off naturally and avoid touching it to prevent the blister from rupturing prematurely.

• Use moleskin patches to protect the blister from contact while walking.

Wash your hands. In some cases, you may need to drain the blister yourself if it causes severe pain, but this should only be done if the pain becomes unbearable. Before draining the blister, thoroughly wash your hands with antibacterial soap and water. Never touch the blister with dirty hands.

• Only drain the blister if it is large and filled with fluid. If it's a small or mild blister, it's better to leave it alone and let it heal naturally.

Clean the blister. Before draining the blister, clean the surrounding skin with water. Avoid using alcohol, hydrogen peroxide, or iodine, as these can slow down the healing process.

Disinfect the needle. You can use a sewing needle to puncture the blister, but make sure to disinfect it beforehand to prevent infection. Purchase rubbing alcohol from a pharmacy and wipe the needle with it. Pour a small amount of alcohol onto cotton or use an alcohol-soaked cotton pad to disinfect the needle.

• Another way to disinfect the needle is by holding it over an open flame until it turns red hot. Use tongs to hold the needle since it will be very hot.

Puncture the blister. Gently insert the needle into the blister. Puncture multiple times near the edges of the blister. Allow the fluid inside to drain naturally, keeping the piece of skin on top intact.

• Do not peel the skin off the blister. You should only puncture the blister to drain the fluid and then bandage it. The skin will eventually dry and peel off on its own.

Apply ointment. After draining the blister, apply ointment to the wound. You can use Vaseline or Plastibase, which are available at pharmacies. Use a clean cotton pad to apply the ointment to the injury.

• Some ointments may cause irritation. Discontinue use if you notice any signs of a rash.

Bandage the blister. Apply a gauze or bandage to the blister. This step is essential to protect the wound during the healing process. Change the bandage twice a day and apply ointment each time you replace it.

• Be sure to wash your hands thoroughly before touching the blister.

See a doctor if complications arise. Most blisters heal on their own, but if complications develop, you will need to see a doctor. If you notice any of the following signs, visit a healthcare professional:

• The blister becomes painful, red, and hot or shows red streaks
• Yellow or green pus appears
• The blister keeps recurring in the same spot
• Fever
• Conditions such as diabetes, heart disease, autoimmune disorders, HIV, or chemotherapy treatments may cause the blister to worsen rapidly, leading to sepsis and cellulitis.

Rule out underlying health conditions. While most blisters are harmless, in some cases, they can be caused by underlying conditions, such as chickenpox, which require different treatment. Based on your other symptoms, a doctor may conduct tests to rule out hidden conditions before treating the blister. If a condition is present, the doctor will suggest appropriate treatment options.

Follow the doctor's treatment plan. Depending on the cause of the blister, the doctor will create a treatment plan for you. Follow all of the doctor's instructions carefully and make sure to ask any questions you may have before leaving the clinic.

Avoid shoes that could cause blisters. If blisters appear after wearing new shoes or uncomfortable ones, it’s best to stop using them. Invest in shoes that fit well and provide enough space for your feet to move comfortably. Wearing the right size and comfortable shoes is key to preventing blisters.

• Choose shoes that suit the activity. For example, wear running shoes when jogging.
• Try to identify any unusual movements causing the blisters, such as a crease in your socks or shoes that don't fit properly.

Apply moleskin pads or shoe inserts. Place a small piece of moleskin or padding inside your shoes, especially in areas where the shoe rubs against your feet, such as the soles. These products help cushion your feet, reducing friction and irritation, which are the main causes of blisters.

Wear moisture-wicking socks. Moisture can create or worsen blisters. Opt for socks designed to wick away moisture. These socks absorb sweat from your feet, lowering the chances of developing blisters and other skin issues.

• Avoid walking for a while if you have a blister – the injury is still painful and hasn't healed yet, so if you want to return to sports, make sure the wound has fully recovered. Don’t play sports if the blister no longer hurts but isn’t completely healed! You may hurt yourself again and cause a new blister.

• Do not use a match to sterilize any tools you plan to use on the blister.
• Seek medical attention if you develop a fever, the blister isn’t healing, appears to be worsening, or shows signs of infection, such as redness, warmth, and pus.
