Blisters are a fluid filled sac caused by heat and/or friction. Many athletes dread getting foot blisters, which can make walking or running a painful experience.
If it is small and closed, leave it alone and take steps to keep it from growing larger – stop walking, change shoes, and cover it with a loose bandage.
If you can’t stop, protect the blister with a donut-shaped moleskin pad leaving the area over the blister open.
If the blister is larger than 1 inch across, it is best to drain it.
To Drain A Foot Blister:
- Sterilize a needle with alcohol.
- Puncture the blister and carefully press the fluid from it.
- Leave the skin intact, do not peel or cut it off.
- Gently wash the area with soap and water.
- Gently smooth the flap of skin over the blister.
- Apply an antibiotic ointment and a sterile bandage.
- Do not use alcohol or iodine – these will delay healing.
- Change the bandage once a day to reduce the chance of infection.
- Remove the bandage at night to let the area dry.
