I have been having my right eye, the corner near the nose swell up for not reason over night in march. it did this last year in march just once and never happened again. but this march it did it 3 times in 3 weeks time. always over night. i first thought sinus so went to my ENT and he checked it out and said no, not my sinus. if it happened again go to my eye dr. it happened a week later and i went to see my eye dr. he said my eyes were totally normal and said it could be an allergic reaction to something my eye was coming in contact with overnight like dust mites in my pillow. SO i bought a new pillow, change my pillow cases every night, wash my hair every night b/f going to bed just incase there was pollen in it, changed all my eye makeup, face wash, EVERYTHING! And it has still happened perioically over the last 3 months!! I'm going crazy trying to figure out what it is? I'm enclosing a picture so you can get an idea of what it looks like. Anyone have anyting like this and give some advice as to what to do?? It never has any pain and will go back down to normal after being up a few hours, and it only happens during the night time. HELP ANYONE
