I too have suffered with itching on my forearms for over 20 years. Some days, I think I'm going insane. I have been to about every doctor imaginable. Right now as I sit here, I feel like a bee is stinging my arm. It starts with stinging, itching, and a very small pin head like mark. With the itching comes a small open sore mark that takes forever to go away. It may go away and comes back in the same spot. I give up with doctors. The only thing that helps is ice and I found that Eucerin Skin Calming Itch Soothing Cream does help. Good Luck to all.
