I have small lumps on my ear lobes - what are they?

Recently I have been noticing small hard lumps on my lower ear lobes. These are underneath where I have 2 piercings (on the lobe) and I have another on the cartilage which I've had for about a year but doesn't seem to have healed.
These lumps are hard and very small, no bigger than the point of a pencil. The one on the ear where I have a cartilage piercing is noticeably bigger than the one which is unpierced.
What is this?
