missingfrontallobe "Snuff box" is fine thanks :).
For the most part, the pain is very much localised to the palmer MCP joint and a region just proximal to this.
elaine anne Pink girlie cast sounds cool – might go with that anyway 🙂
Dr_Death – it wasn't really a true FOOSH injury – I was pulling up on the bars trying to manual a ditch, mis-judged it and landed heavily on the up slope and must have over extended my thumb as I went over the bars 😕
Re the co-lateral ligaments, After a quick google anatomy lesson, the pain is roughly around the origin of the RCL so I guess that could be a source. Everything feel stable though so poss just a strain.
Thanks for the info – don't you just love relaxing after work 😉
