A doctor friend looked at this picture and told me to go to my doctor and be checked out for an Autoimmune disease. Any other opinions before I go to my appointment would be greatly appreciated. I had been experiencing a slight rash on my arms and then this showed up on my legs overnight. They are warm to the touch and not especially raised. Not too itchy, if at all. I am extremely stressed right now, and I wonder if that has something to do with it. No changes in diet or environment lately either.
