My Min Pin mix has a lump by his eye.

My Min Pin mix has a pea sized lump on the outside corner of his eye. It is not touching his eye or the eye lid. It has a rough exterior and it seems to be bothering him because it looks irritated like he has been scratching it. The hair on the lump is gone. He also has a smaller one below his eye(also not by his eye or eye lid). Please help
