I woke up with it today, it covers most of my face, including cheeks and forehead. It feels very rough, like scales almost, too, with some raised bumps scattered throughout and my skin is very flaky in some areas, like my forehead and my jaw line.
I would assume it was an allergic reaction, but the only thing I've changed is that I recently found out I have Celiac's Disease, so I cut out gluten and have not eaten any in a week.
I also started my period yesterday.
