Without examination confirmation of a diagnosis is tough but it can be allergic or irritant contact dermatitis like washing dishes without wearing gloves,contact with harsh detergents,soaps and lotions that contain perfume,sweat dermatitis or eczema.
Wash the areas several times with fresh water. Do not use any cosmetic products at the sites.You can apply some calamine lotion at the rash as it will help in soothing the skin. Use good quality moisturizers to prevent moisture loss from the skin.Also apply a mild steroid cream like dermacort on the hands. During the day, hydrate and protect hands with a protective and moisturizing cream. At night, repair them with creams formulated from glycolic acid. For a more intensive nighttime treatment, apply cream and then cover hands with gloves or socks.Also wear gloves while doing household work.For the itching take OTC antihistaminic like Benadryl or Claritin.
If still the symptoms do not improve then pls get a clinical examination done by a dermatologist. Fungal infections have to be ruled out then.
Hope it helps. Take care and pls do keep me posted on how you are doing or if you have any additional queries.Kind regards.
