BH came off the quad bike on the road last year, same thing - used his arm to protect his head, knowing he was risking injury to the arm.
Had sore weak arm and grumbled for months. After lambing

, went to doctor, yes he'd fractured a small bone in his wrist and it was now too late to do anything about it.

So it's healed now but will never be as good as it was - or as it would have been if he'd had it seen to in the first place.

So, Sally - if there's stiffness that persists beyond a couple of days... get it looked at! (:wagging finger: icon required.)
