Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Your husband's symptoms are pointing towards
allergic reaction only leading to itchy and swollen palms.
It can be due to any soaps, detergents, any chemicals, foods etc.
So first of all get an
allergy test done to rule out the exact cause of allergy.
Avoiding exposure to allergen is the best way to reduce allergy attack.
For now you can start using hypollergic detergents, soaps and cosmetics and also take anti allergy medicine if there is a reaction.
Also applying
Caladryl lotion can soothe the skin.
Do ice packs to reduce inflammation and swelling..
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
