Had to reply just to let you know someone is out here!!!  Good luck with the GP appointment - you sure they haven't given you some old Scammell with no PAS to drive, and you've pulled muscles!!  Got my HGV medical in a couple of weeks - reckon my unassisted eyesight will be marginal.  Why is it the test for trcuk drivers is worse than for private pilots??  (At least I don't drive for a living so not quite the pressure).
Treat it as an unexpected rest in bed .........maybe.......  - cheers, A
