Anyone have dermatographia? It can go with mast cell issues but doesnt have to. (For those who dont know, its sometimes referred to as skin writing. Its when even light scratching of skin leads to a local wheal and flare reaction. So if you write a word on your skin for example, 5 min later the word will be visible as a red/pink raised rash. Can be itchy too. So scratching can set up a vicious cycle)

In a mild form, I have this occasionally. CFS/ME includes connective tissue pathology just as SLE does. I think this is just a manifestation of this.
