If your not sure its worth going, I thought i twisted my ankle a few years back, wasn't in loads of pain and a bit of swelling, went to the GP after two days of hobbling and increased swelling to find out i'd broken my tibia and had to wait in hospital for 2 days waiting for the swelling to go down before they could screw it back up,
Google + You, doesn't = Doctor
Plus i'm sure any doctor would be happy to make you feel better about it than treating some drunk ****t
