Swelling around eyes

Please help!!! I’ve always had eczema and recently my new makeup routine has been triggering it. My entire face was red, burning and itchy non stop. The cream I have been prescribed is doing nothing. Today, I woke up and the eczema has cause the underneath of one of my eyes so bad it doesn’t open properly. I know I need to temporarily stop hang the makeup, but I need to go out later and it looks like I’ve been hysterically crying for hours. What can I do to immediately reduce the swelling so I can open my eye properly?
