In brief: Epidermoid Cyst

Epidermoid cysts usually don't cause problems unless they get very large or the cyst wall ruptures, exposing the inside keratin to the surrounding tissue.
This is a problem because the contents of an epidermoid cyst are very irritating to the tissue around the cyst. A ruptured cyst can get red, swollen, and painful. Your cyst has ruptured, see a surgeon.
