Blistercare

It’s usually best not to burst a blister, as the skin protects against infection. A hydrocolloid blister plaster can cushion it, relieve pressure and support healing. Keep the area clean, and if a blister bursts, keep it clean and covered. Seek advice if it shows signs of infection.

Generally no — an intact blister protects the skin underneath from infection, so it’s best left alone and simply protected with a cushioned plaster. If a blister is very large or painful, seek advice rather than bursting it yourself. If one bursts naturally, keep it clean and covered.

Wearing well-fitting footwear, breaking in new shoes gradually, keeping feet dry, and using protective cushions or anti-friction products on vulnerable areas can all help prevent blisters. This is especially worthwhile before long walks, hikes or events where you’ll be on your feet.

Seek advice if a blister is very large, extremely painful, keeps recurring, or shows signs of infection such as increasing redness, swelling or pus. People with diabetes or circulation problems should take extra care with foot blisters and seek advice promptly.
