Hey, since May of this year I have had this weird 'rash'. For the first few months I thought it was a reaction to food. It's completely flat, red, 'blotchy' looking. Then recently, I noticed when I raise my arms above my head for a while it goes away completely, and then gets worse when my arms are straight down for a while. (it's only on my forearms, somewhat up my upper arms) Can anyone point me in the right direction? My doctor doesn't even know. Thank you

Tracy
