Can swelling from periorbital/orbital cellulitis come and go? theres 1 sided swelling of the lid with no redness of the eye or discharge. worse in am

Cellulitis: Have you actually been diagnosed with periorbital cellulitis? If so, then you should be on antibiotics. In general, one can say the eyes are more swollen in the morning so any tendency to swelling will be worse at that time.

Orbital cellultis: Agree with Dr A, orbital/preorbital cellulitis isn't an easy diagnosis, antibiotics, even intravenously should be adminstred promptly and for a good duration; wish you well

AM puffiness: In some people puffiness of eyelids in the morning upon awakening are common and are felt to be a result of lack of eye blinking during sleep. Other causes include allergies,infection or other inflammation. Cellulitis, a more serious cause of eyelid swelling, would not merely come and go and would be treated with oral antibiotics and possibly topical ophthalmic antibiotic ointment as well.
