Chalazion: The most common cause of your eyelid lump is a chalazion. This is a chronic infection in one of the eyelid glands. Sometimes, using warm compresses regularly over 1-2 weeks can help shrink this. Sometimes, a minor office procedure is done to remove it. If the lump doesn't get better on it's own, then see your eye doctor to discuss your options.
