Styes, though harmless in the long run, are possibly the most annoying eye problem. A stye is a tender, often red, lump that forms on the edge of the eyelid. A lump may sometimes form on the inside of the eyelid which is called a chalazion. A stye often begins its short life as a pimple type of lump on the eyelid and expands in size for three days. After two to five days, the stye will break and drain on its own. You’ll likely feel completely normal in a week. However, styes can sometimes be painful. Chalazions, on the other hand, take more time to grow and will likely not cause any pain. However, chalazions may affect your vision depending on where they develop and how large they grow. They often go away within a month with no treatment.
