I woke up and my eyelid was swollen for some reason, just the right one and just the upper lid. The day before it felt a bit discomforting when I would touch it to wipe my eyes or when I closed it suddenly. Now it is swollen and prohibiting me from wearing my contacts. Recently, my roommate has brought her cat over to live with us, but I have never shown allergies to this cat before, or any cats. We have also recently moved and I have been around a lot of dust, to which I have a mild allergy. I also have a sore throat on the right side, but I'm not sure if the two are related at all.
