A blister is a bubble of skin filled with clear fluid ranging from pinpoint size to more than an inch in diameter. Common causes of blisters include friction and burns. Try to keep a blister intact, if it isn't too painful. Intact skin over a blister provides a natural barrier to bacteria and decreases the risk of infection.

What to Expect

  • Fluid-filled skin bubble
  • Usually heals in two to three days

When to Rush to the Doctor

  • Swelling around a blister
  • Redness
  • Increasing pain or warm skin
  • Pus/yellow discoloration
  • Blood filled

How to Drain a Blister

  • Wash your hands and blister with warm water and soap
  • Swab the blister with iodine or by rubbing alcohol
  • Use a sterilized needle to puncture the blister
  • Apply antibiotic ointment and cover with a bandage
  • Cut away all dead skin after a few days

Home Care

  • Cover small blisters with an adhesive bandage and large ones with a porous, plastic-coated gauze pad
  • Don't puncture a blister unless it is painful or prevents you from walking or using your hands
  • To relieve blister-related pain, puncture the blister with a sterile needle. Ensure you clean the blister with iodine. Apply an antibiotic ointment to the blister and cover it with a bandage
