How to heal an eczema outbreak?

ive had eczema since i was a baby but since im 15 now i know how to control it for the most part and i can keep my skin clear, but RANDOMLY the areas where i will usually get red patches started itching and burning and even tho i applied cortozone 10 and coca er to them, i woke up with terribly irritated inflamed and super red patches. each elbow had a patch at the crease,and my left leg had a awful rather large patch behind my knee. i hate it so much cuz its summer and i want to wear shorts and a bikini and when this happens i cant. so i hide my legs in jeans which its to hot for. im a runner, i run everyday pretty much and my mom says i got this outbreak from sweating so much probably cuz when i came bakc form running i was itchy. I HAVE TO GET RID OF THIS ASAP! i want it to be gone in a day or 2 days at most. im soooo self concious and its severly affecting my cofidence. i dont feel pretty with it and i dont want ppl staring and thinking i have some god awful contagious disease...which thats wat it feels like. HELP! ive tried milk baths,oatmeal baths,cortozone,aquaphore,vitamin E cream, and elidel ointment, tons of lotions, NOTHING WORKS! how long till it heals??? my boyfriend is visiting next wednesday and it must be gone! plz give me helpful advice or something new i should try :(((
