Do you have any rashiness on them? Any spots or bumps? Does it get worse when washing dishes or hands in warm/hot water? Hand eczema is a common disorder that can be treated with steroid based creams...research pictures of it on the web. I have had that for 5 years now, and my hands itch every day, so bad that the skin will get cracked and bleed, if I don't use the medication every day. It's unknown what the specific cause is, but many times it's related to an allergen. Good luck!
its better to go to your doctor and consult.It might be the skin allergy.
