I can’t tell you how many times I ‘ve scratched an invisible itch. As odd as this may sound it’s so very true. Having a chronic illness that deals with nerves it can cause a really insatiable itch in different parts of the body. I tried lotions of all types, nothing helped. Finally when talking to a fellow warrior about the issue she suggested benadryl. Really…. I was just as confused as you. Surprisingly it worked. Now benadryl is my go to for chronic itch. This is one of the times a hack actually worked. Sometimes you have to go out on a limb…especially with chronic illness.
