I'm new to this area and would like to thank you for talking about arms itching and the bendadryl spray. I went out and purchased it to see if it would work on my arms. They itch so bad I scratch them raw. The spray seems to be working for the most part. It has slowed down the itchy feeling so I can tolerate it and not itch. My husband is happy about it because it says I also scratch my arms in my sleep throughout the night and the movement keeps him awake. Thanks again for the info!!
