A sty is a relatively common bacterial infection near the root of the eyelash. It looks and feels like a pimple as it is red and filled with pus. Sties usually start and resolve within 1 or 2 days.
This common infection usually develops near the root (follicle) of an eyelash. You may have more than one sty at a time or several in succession.
A sty starts as an itchy or painful swelling on the eyelid. Your eye will be red and you will have tearing and blurred vision. It may feel as if something is under your eyelid.You can find good relief with applications of warm compresses for 5 minutes, several times a day. This helps to decrease inflammation and pain from the sty. When the sty comes to a head
and bursts on its own, clean your eye with damp cotton balls and throw them away to avoid re-infection.If the sty is swollen after a few days or is painful and affects your vision, call your doctor. Your doctor may need to lance the sty to drain the infection.
