Suggest Remedy For Severe Eczema

What is the safest way to get my eczema under control? I have broken skin from scratching. I cannot sleep at night because it feels like something is eating away at my skin. I have had eczema all my life and have followed the basic routines all my life to prevent a breakout like I am experienceing now. I have a doctors appointment today wit a new doctor. I want to come prepared. I have rash over every surface on my body including the inside of my eyelids.
