HELP!!!! SO. ITCHY!

Hollie • ♥️Had my first! A sweet baby girl!♥️
For the past couple days I've been severely itchy from my neck to my butt. I've taken oatmeal baths, pretty much keep cocoa butter on my skin, and have even tried goldbond itch relief lotion and NOTHING works for more than a few minutes. Does anyone else have such severe itching?! Im going insane of here! Please please help!
