This abscess is generally a localized staphylococcal infection and you may get more than one sty at a time or several in succession.
Sties respond well to treatment, but can recur.
If untreated, sties can eventually lead to cellulitis of the eyelids, a more serious condition. They are neither contagious nor a sign of cancer. Sty Signs and Symptoms Redness, swelling, and pain in a localized area of the eye. Slightly blurred vision. An examination of the eye generally confirms this infection.
