is raised section of skin which is full of a watery substance and is usually caused by
aggravated rubbing or burns
What to look for
one or more bubbles of skin
filled with clear fluid, ranging from pinpoint size to more than one-half inch in diameter
usually accompanied by pain, swelling and inflammation.
Most blisters form as a
reaction to irritation or other damage to the skin from an external source, although some
can result from a disease or other ailment. Blisters can form on any exposed area.
Blisters can result from
the rubbing of skin against another item such as from the wearing of new shoes, which
causes an abrasion to form. This can happen quite quickly and is very painful.
Flames, steam, or contact
with a hot surface can raise blisters, as can excessive sunburn or exposure to other types
Skin may blister when it
comes in contact with certain chemicals, cosmetics, and many other toxins.
Many people develop
blisters as a reaction to taking certain oral and topical drugs.
Blisters are a common
symptom of many infectious illnesses, including chickenpox, cold sores, herpes
simplex, shingles, and impetigo.
Most blisters caused by
friction or minor burns do not require a doctor's care. They can usually heal on their own
with a little help from you.
Soothe ordinary friction
blisters with vitamin E ointment or an aloe-based cream. Do not pop a blister unless it is large and
too painful to leave. If you have to pop it, use a sterilised needle or razor blade. Wash
the area thoroughly, then make a small hole and gently squeeze out the clear fluid. A dab
of "Dettol" can help protect against infection.
If the fluid is white or
yellow, the blister is infected and needs medical attention. Do not remove the skin over a
broken blister; the new skin underneath needs this protective cover. For blisters caused
by chemical contact or disease see a doctor.
