I wanted to share with you all the cure for this that worked for me I swear by it. I almost scratched both my forearms off. It’s awful and I want to help anyone suffering with this misery. Morninga oil get the purest you can find. I believe it’s damaged nerves from sun but I don’t know for sure. Turns out morninga oil heals nerves even topical. It worked for me! Please buy some you can get it online but make sure it’s pure! Rub it on the areas until penetrated a few times a day until gone! Bless you all and thank me later! Xo
