Blisters

---

Blisters are lesions of the feet that are filled with pockets of fluid, caused by rubbing, friction, or burns.

Blisters form as a defence mechanism to protect skin from further damage and aid healing.

Friction- From foot deformities, or wrinkling socks against skin.

Rubbing- Potentially from ill fitting footwear

Burns

Drug Reaction- Blisters can develop as a reaction to certain drugs

Infection- Blisters can occur as a symptom of some infectious conditions for example, chicken pox or shingles

• Redness
• Pain or soreness
• Fluid filled lesion on the skin

Self Treatment:

If the blister is still intact and has not popped:

• DO NOT pop the blister
• Blisters tend to heal on their own if left alone and the cause of the blister removed
• Cover the blister with a plaster or dressing to keep it clean. Be careful not to apply tape to the blister, as this will de-roof the blister once plaster/ dressing is removed

If blister has popped:

• Clean with mild soap and water
• Apply antiseptic
• Keep blister covered or apply soft redressing like Compeed to help skin heal

Blister prevention is essential in maintaining foot health:

• Ensure shoes fit well
• Cushion and pad over areas at increased risk of pressure e.g toe deformities
• Ensure socks fit well

• If blisters become painful
• To check if orthotics maybe helpful to relieve pressure areas
• For dressing/ footwear advice
