Hi, I've just read something really interesting to me on Arthritis Research. Once of the symptoms of vasculitis is Raynauds (which I have been told I've got, as well as other autoimmune disease). It stated that feet and hands more at risk. I do know I have symptoms in my hands, the white numb fingers turning red and burning hot, but I didn't know that a red pen like line at the base of the nail bed in feet was a symptom. I always wondered why I had these red marks on my toes. Now I know. Don't know what they do but hey ho, we can't have everything.
