I had an accident about 2 years ago (fell down the stairs with a hoover) i've had my foot x-rayed twice as it still plays up and it hurts bad. advice?

Possible occult frac: You could have an occult (hidden fracture) that does not show up on xray. I recommend an MRI of the injured area to see if there is a hidden fracture or other soft tissue injury. Then proper treatment can be rendered.

See below: See another doctor. You may need advanced imaging such as a ct or MRI scan to determine the problem.
