What causes the inside corner of your eye to swell?
Dacryocystitis is inflammation in one of your lacrimal sacs. It's more common than dacryoadenitis. Lacrimal sacs in the inside corner of your eyes collect tears that drain out of your eyes before they enter your tear ducts. Blocked tear ducts (nasolacrimal duct obstruction) are the most common cause of dacryocystitis.
