UK: Injured wrist two weeks ago. GP or Minor Injuries?

So about two and a half weeks ago, I came off my bicycle. Long story, another idiot was involvd.

Wrist hurt a bit, but just felt like a sprain.

But two weeks later, the pain has not decreased, and has gotten slightly worse. it now definitely feels to be on the wrist bone.

So I should really ge tit checked in case of a fracture, but do I go to Minor Injuries at my local hospital, or is this a simple job for a GP?

(Not really sure what sort of timeframe for an injury Minor Injuries are good with)
