It’s a skin condition. I’ve had eczema from childhood and, unfortunately, I’ve passed it on to my son. We both use steriod cream (betnovate) which suppresses it for a while, but doesn’t completely irradicate it. I’ve believe it can be aggravated by stress - although I try to stay as stress-free as possible 'cos of the MS!
I always wear rubber gloves when washing up or using household products and use perfume-free soap & handcream.
I’m sure your cream will stop the itching quickly.
