Open all pages about Blisters

A blister will usually heal on its own. To help it heal and stop it getting infected, cover it with a plaster or dressing and do not burst it.

Blisters are lumps under your skin that can be filled with clear fluid, blood or pus.

If a blister is very big or painful, a GP may drain it using a needle. If it's infected, you may need antibiotics.

You can help avoid blisters by wearing well-fitting shoes, only wearing new shoes for short periods at first and wearing thick socks while exercising.

Blisters are fluid-filled bumps under your skin that you can get if your skin is damaged.
