My hands get like that sometimes, if I'm on the computer too long or if I have to hold up something for very long. I crochet when my hands get stiff. Try putting on lotion and massage right above your wrist and then deeper in the palm of your hand. I also give my dishwasher a break and use really hot water and was dishes. Also you might try moist heat. I have a long moist heating pad and I roll it into like a muff and put my hands inside.
