What is dyshidrotic eczema?
Dyshidrotic eczema (pompholyx) is a form of eczema characterized by tiny intensely itchy blisters on palms, sides of fingers, and sometimes soles of feet. About 5–20% of hand dermatitis cases.
Triggers include stress, sweating, contact allergens, and seasonal changes. Treatment focuses on flare control and trigger avoidance.
Do I have dyshidrotic eczema? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Genetic predisposition plus triggers — stress, sweating, allergic contact (nickel, cobalt, fragrance), infections, seasonal changes. Often coexists with atopic dermatitis.
Is it contagious?
No.
High-potency topical steroids are usually needed on palms — over-the-counter hydrocortisone often isn't strong enough.
Can it be treated online?
Dyshidrotic eczema is well-suited to telehealth — photos confirm. Severe cases with secondary infection, treatment-resistant cases — may need dermatology referral.
How dyshidrotic eczema is treated
High-potency topical steroids — clobetasol, fluocinonide — palms and soles have thick skin. Use for flares; rotate with non-steroid emollients between. Tacrolimus or pimecrolimus for maintenance. Patch testing for recurrent severe cases. Phototherapy for refractory. Cold compresses during acute flare. Treat secondary infection if present.
Self-care while you wait
- Avoid known triggers — sweating, certain metals (nickel), some soaps
- Gentle hand washing — pat dry
- Apply moisturizer (Vaseline, CeraVe) multiple times daily
- Wear cotton-lined rubber gloves for wet work
- Manage stress
- Don't pop blisters
- Cool compresses for relief
- Identify and avoid contact allergens (rings, watches)
How long does it last?
Each flare 2–3 weeks. Recurrent pattern — flares triggered by stress, sweating, exposure.
Frequently asked questions
Can I pop the blisters?
Don't — risks infection and slows healing.
Will sweat make it worse?
Often yes — keep hands cool and dry. Cotton-lined gloves for outdoor work.
Is it the same as athlete's foot?
No — different mechanism. Dyshidrotic is non-infectious eczema variant.
Will it go away forever?
Usually chronic with flares and remissions. Long-term management possible.
Are there any food triggers?
Nickel ingestion may worsen some patients with nickel allergy. Otherwise food rarely a trigger.
