Swollen eyelids occasionally, was told its contacts & allergies. Swelling usually goes away in 1 day, but both eyes for 3 days now. What can I do?

See doctor. Since there is no itching, this may be from angioedema. But if itching is present, then a contact allergy (including eye makeup , eye drops etc) may be the cause. It is time to consult your eye doctor to find out.
