pityriasis rosea (PR) :((

Brianna • 26, married in Oct 2013, first Baby. SUPER EXCITED!
So I have pityriasis rosea (PR) a SUPER annoying, itchy rash that has formed on my trunk and now my upper legs. It's not contagious! It is brought on by stress/low immune system and is self limiting (goes away on its own). At first it shows up as one circular welt that looks like ringworm, then spreads across your trunk/upper body.
Has anyone else been diagnosed with this??
What's some ways you help eliviate the itch??
(The picture was the very beginnings of it, now it's SOOOO much worse) :(((
