Blisters are puffy, fluid-filled pockets that occur in the top layer of the skin. They occur after the skin gets damaged as to protect the skin and promote healing of the injured area.  

What causes blisters?

Those who walk and run long distances won’t be strangers to foot blisters. When the skin undergoes friction, such as repeated rubbing against the inside of the shoe or spending long hours on the feet, a blister can form. Other causes include:
  • Skin burns
  • Insect bites
  • Infections
  • Excess moisture/sweating
  • Excess pressure
  • Allergies
  • Trauma
Wearing poorly fitting shoes — or new shoes that haven’t been broken in – can often set the wearer up for blisters.  

What are the symptoms?

The main symptom is the appearance of a bubble-like, raised portion of skin. Other symptoms that may accompany the bubbled skin include:
  • Redness
  • Itching
  • Tenderness
  • Pain

How do you treat blisters?

Treating blisters involves both managing the current blister and taking the right measures to reduce the risk of it coming back. Protect the blister with a loose, clean bandage until the body absorbs the fluid in the blister and the blister thoroughly heals. Avoid wearing tight footwear that will irritate or burst the blister as that can leave it vulnerable to infection or further damage. When running or walking, wear comfortable, well-fitted shoes and clean and dry socks. If the blister worsens, doesn’t heal, becomes discoloured or shows signs of infection, we recommend that you see one of our podiatrists or a health professional immediately.
