Puffy, Swollen Eyelids- No other symptoms?

I have been waking up with Puffy and Swollen eyelids for about a week now. It is only the top from my eyelid crease to the bottom of my brow. I have no other symptoms other than I can FEEL when they are puffy. They go down throughout the day, but never fully. When I wake up they go right back to being big honkin puffers. I went to the doctor and they gave me a 5-day taper of prednisone and a 5 day antihistamine perscription. These did NOTHING. I have stopped wearing makeup and I changed ALL of my bed dressings, not just my pillows. I have taken benadryl and 12 hour allergy meds and nothing has helped. NONE of my routines have changed, nor have i used anything new or eaten anything different. I have no idea what else to do. PLEASE help.
