Can be abscess: Sounds like you have an abscess. Time to go to your doctor and get it drained.

Infection: Sounds like you have an infection. The lump on your ankle may be an abscess that is trying to drain or a cellulitis (generalized infection of the tissue). Regardless, you should see a doctor and get it treated. This may include taking a culture then antibiotics.

Pus: Appears as if you have an infection and should get it treated with antibiotics before it spreads.
