The rash randomly gets more red, is sometimes hot to the touch.
Yes I get it and I get it on my arms and legs too!
I know that there is an autoimmune illness which causes a rash often on the nose and cheeks, think it's possibly lupus, why don't you look it up and see if your symptoms fit? Many of these illnesses have similar symptoms so doctors don't always diagnose the right one first time or change their mind about what you have when further symptoms appear. I only know about this cos one of the GP s at the practice I go to thought I may have it.
Thank you Fran.
