t know how
itchy arms happens but I found something that made the super itchiness in my
arms stop. A friend who's had a life-time of eczema told me about bleach baths. So I did as he advised, I took a cup of bleach (Clorox) and poured it in a bath tub of warm/hot water and got in it for 10 minutes. The first time I did this ended all of the itching. Four days later I did this bleach bath again because I thought I felt the itch returning and again it worked.
