In reply to Jack McKechnie:
Have a search through the Forums here for similar 'sore finger' posts and you'll find a whole heap of useful and not so useful information to take away. Mostly the advice can be summarised as:
a) If it's really bad rest, if mild pain/ discomfort then go easy on it and tape it up
b) Do some therapeutic exercises to keep it moving and get the blood flowing into the finger. Recovery is slow if it is ligament/ tendon damage and totally dependent on nutrients from the blood getting to where any damage might be. Any exercise, even cardio that doesn't use the finger at all will increase blood flow and speed up the healing process. (my two cents)
c) Gradually build up the amount you use it according to how much it hurts and hopefully it will heal nicely and you can get back to crimping hard!
