Swollen eyes. Swollen eyes may result from allergies. If your eyes itch, try zaditor (ketotifen) twice a day for a few days. If your eyes are watering profusely, you may have pinkeye. Try artificial tears every few hours for a day. If not better, call your local ophthalmologist.
Swelling. Start with getting more sleep and applying ice compress. You should have an examination to make sure you don't have thyroid eye disease or any other condition.
