A sty is tender, red bump on the eyelid caused by an acute infection or inflammation of the oil glands in the eyelid. If the gland is blocked, the oil produced by the gland will become congested and cause the oil to protrude through the wall of the gland forming a lump. A sty can grow on the upper and/or lower eyelid and cause tenderness and burning.
