The inflammation is caused by a sensitivity to a common bacteria found on your skin. When the openings of the small oil glands around your lashes become blocked by inflammation, a small tender swelling will occur in the lid. This is known as a chalazion.
The chalazion will often vary in size over a few weeks and can discharge spontaneously after hot compresses and lid cleaning. A small proportion of the chalazia will form hard lumps on the eye lid, which, if present for a few weeks can be incised and drained under local anaesthetic.
Sometimes the chalazion may cause a spreading infection along the surface of your lid, which might need a course of oral antibiotics, but this is rare.
