Are small and itching “blisters” on your fingers driving you mad?

If you see “blisters” on your fingers and they itch, these may not be the typical blisters that result from a burn.

“Itchy small blisters on the fingers are often simply a condition called dyshidrotic eczema, a form of dry or irritated skin,” says Dr. Joel Schlessinger, MD, board certified dermatologist and cosmetic surgeon with a private practice in Omaha, NE.

“It is important not to pick at them or open them up, as that can result in more issues and prolonged irritation,” says Dr. Schlessinger.

“Instead, try to moisturize them or use a topical steroid if available such as 1% hydrocortisone (www.LovelySkin.com/FixMySkin).

“This can result in improvement, but if there is a continued irritant such as handwashing, detergents or a contact allergy to rings or clothes, these will have to be avoided to allow the area to improve.

“Many times I am asked what the ‘water’ or ‘fluid’ is inside of the blisters. This is only serum (a form of infection or trauma-fighting fluid) that is sent to heal the area.

“Opening up the area or washing it away delays healing, so it is best to avoid unroofing the blisters.”

And no matter how much they itch, do not scratch them.
