Xray: Did the skin get punctured? Could be infection, broken arm, torn ligament, hematoma (blood underskin) or dislocation. Did an xray now and see your doc. That's too long for these symptoms.

See your doc: Possible injuries include fractures, sprains, infections, dislocation. You are not getting better toughing it out, you could get worse. Please see a doctor.
