Are these festoons? Do festoons come and go? Do festoons ever turn red? What are treatment options or other possible diagnoses?

Recurrent swelling under both eyes which started a year ago. The area swells up, turns red, & then it goes away. Left side is always worse than right side. I've seen my GP & my dermatologist; neither have any idea what these are. I have a severely deviated septum. I was told to double my allergy meds & begin nasal steroids in case it was allergies. It hasn't helped. My GP even tested me for lupus. I only wear makeup on my eyebrows & constantly wear SPF. What are these? Please help.
