I knocked my ankle quite bad on the vaccum cleaner two days ago it has swollen and painful and brused have i broken it. i can weight bear but sore?

Sprain or bone contu: It sounds like either a ankle sprain/strain or bone contusion. The worst case scenario in your history is possibly a chip fracture, but none of these pathologies require surgery initially. Wear an ankle brace for stability, rest, ice and elevation. Taking an Ibuprofen can help with swelling reduction as well.

Probally not: Usually broken bones cause enough pain to limit walking. You should see your local doctor for an evaluation and treatment.
