i have what kind of feels like a twitch in my eye not the normal twitch that i have had in the past. almost like a bubble. i have had recent sinus issues, been on antibotic, got a fever blister on noce that got infected. my doc had me do the neti washes and inclued some antibotic ontiment in the wash. any chance the sensation i am feeling is a clogged tear duct? what do i do to get this to stop annoying me.
