Oddly enough, I woke up with the same thing today. I do not have a sty, as I have had them many times before, and this is not the same. I think I have a clogged tear duct, as the area under my eye/by my nose is very sore and a bit puffy. No issues on the other eye. I am going to the eye doctor today, as I have had a clogged duct before and needed an antibiotic.
