What Causes Severe Itching On The Hands And Feet?

For a few years now, I’ve been suffering on and off from severe itching. It happens a few times a year, and it happens during all seasons. It will start off with itching usually in my hands and feet and over the nexts 1 to 2 weeks spread all over my body. My back, hands, feet, legs, even my head itches sometimes. It’s not from dry skin and keeps me up most nights. I’ve tried different any itch lotions and nothing works. Any advice would be appreciated.
