Yes, I was diagnosed by a rheumatologist at Mayo Clinic, who I still see. The face/ear flares are similar to the ones in my feet. There’s redness, burning, and skin is very hot to the touch. Sometimes there’s some very slight swelling. I used to get swelling in my feet to the point where I could not walk. If you haven’t been diagnosed yet, take photos of the flares to bring to your doctor. It’s helpful for diagnosis. Hope this helps you.
