Hello lupus friends, a week or so ago I found a crescent shaped rash just at the edge of my underarms - no itching, a little painful on pressure. It was pink and flaky and is now brown and crusted. I think it is lupus-related because I am having other symptoms, but I have only had sun rashes before, so am mystified. Has anyone experienced something like this? Thank you all for your posts and the kindness that shines out of this forum.
