I Itch All Over. There's No Rash Or Flaking Skin.

I itch all over. There's no rash or flaking skin. My back, head and feet are especially itchy. My medication hasn't changed, nor diet or detergent. ( I just remembered that in the past, stress has caused me to itch and break out in hives. There are no hives now, but my husband of 45 years died 6 1/2 months ago and I am somewhat overwhelmed.).
