I've had this problem frequently for the past two-three months since I moved back to southern California from northern California which I lived for three years. Before this I was still living in southern CA and also in Colorado.
My left lower eyelid would get swollen as if there was a build up of fluid, so I do the a hot and cold compress to see which one helps, and also take Benadryl. After a day or so it seems to go away. Now it is on my upper eyelids only, one eye at a time. Normally it is the left and today it is the right.
Takes a few days but it goes away. It also makes the sides of my face itchy but my eyes never have problems. Sometimes the night before it happens they get real dry and itchy. I figured it was my pillows since I normally use Febreze Allergen Reducer and had changed the brand, so I switched back to Febreze. I also washed my bedding and pillow cases to help. I have hay fever and take an over the counter day time allergy med but only have to now that I'm here in southern CA
I've read to change the actual pillows which I'm going to do today, but if there was anything else I may be able to try? The over the counter allergy stuff if different than what I used to use, which was Zyrtec when it was only rx form. Would that also help if I switched?
Thanks!
