G'day Andy,

When someone like yourself has an injury the best thing to do is head down and get an xray. You may have a distal ulnar tip chip fracture. Assuming this is clean you may have sprained your collateral ligament there or damaged the TFCC which would be better imaged with an Wikipedia reference-linkMRI but I would only suggest that if you are a high level athlete or normal and not reponsive to rehabilitative treatment after a suitable attempt. Hit the physio up for management regardless, as your GP will be relatively useless in giving you advise regarding how to get well quickly.

Best of luck and keep us posted on your xray results.

Cheers,
SPPAWA
