Question: are chalazions and styes the same?
Answer: Most styes occur along the edge of the eyelid. When a stye occurs inside the eyelid, it is called an internal hordeolum (say "hor-dee-OH-lum"). A chalazion (say "kuh-LAY-zee-on") is a lump in the eyelid. Chalazia (plural) may look like styes, but they are usually larger and may not hurt.
