Health Matters: Blisters - Saddleworth Independent

Uppermill pharmacist IAN STRACHAN examines blisters

PHARMACIST: Ian Strachan

BLISTERS ARE small pockets of fluid that form in the upper layers of skin. This fluid serves to cushion the damaged tissue beneath, thus protecting and accelerating healing.

Blisters are typically filled with clear fluid known as serum, although occasionally can be filled with blood when inflamed or infected.

Causes of blisters

Friction of the skin is the usual cause although contact with chemicals like detergents is also a common culprit.
Heat from sunburn or scalds may also contribute.
Finally some medical condition like chicken pox, impetigo, and even cold sores may be associated.

Treatment

Most cases of blisters can heal naturally and do not require medical attention. As new skin grows, the fluid gathered inside the blister will simply be reabsorbed as the surface skin dries then peels off.

For friction blisters the unbroken skin provides a natural barrier, so avoid piercing those blisters and encourage the skin to peel off naturally after healing.

With burst blisters once again avoid peeling the skin off. Friction and burst blisters respond effectively to a Hydrocolloid Gel dressing, available from pharmacies.

Branded Compeed, or other equally effective brands – these plasters not only protect and cushion the blister but encourage healing and minimise discomfort. As a pharmacist I’ve had many positive comments about Hydrocolloid plasters.

For blisters which are on your feet, avoid those shoes which caused the problem, at least until they heal.

Most blisters heal naturally in three to seven days but your pharmacist may refer you to your doctor when blisters appear infected, are painful, or keep recurring. Infected blisters are filled with yellow or green pus and are typically painful, red and hot.

PREVENTION

There are a number of ways to avoid getting blisters:
