I've honestly never heard of a rash being associated with pms. I would ask your gyno.

I too have had a rash for the past seven months. After several biopsies and 2 cycles of prednisone I have not answeres. Rash is on my neck and face. It went away while I was on double doses of prednisone. When I went to single doses it came back. After I stopped all together I've noticed the rash is fierce when I ovulate and calm during my period and the week after. I've been to several specialists with no ansers.

When I ovulate or my hormones are high, my cheeks looks as if they are burned. It doesn't hurt, it just goes away after a few weeks. Also my mother when she ovulates gets a red rash on both arms. I have no answers. But its been this way for years and I just deal with it.

I came down with a non-itchy rash right after I ovulated too. The rash is mainly on the front of my thighs, a very little bit on my calves, and a bit on my arms. It flares up redder when I take a warm bath. (Just little pin-pricks that feel slightly rough when I run my hand over the rash.) I also have a few lymph nodes that feel a little bigger in one side of my groin.
