To relieve any pain, use an ice pack (or a bag of frozen vegetables wrapped in a towel) on the blister for up to 30 minutes.
To protect the blister and help prevent infection:
cover blisters that are likely to burst with a soft plaster or dressing
wash your hands before touching a burst blister
allow the fluid in a burst blister to drain before covering it with a plaster or dressing
do not burst a blister yourself
do not peel the skin off a burst blister
do not pick at the edges of the remaining skin
do not wear the shoes or use the equipment that caused your blister until it heals
Your GP might burst a large or painful blister using a sterilised needle. If your blister is infected, they may prescribe antibiotics.
They can also offer treatment and advice if blisters are caused by a medical condition.
