Cheers Andy,
I've never had any need of physio before (in fact I suppose I've never had a 'real injury' before now... Apart from burning a layer off my whole face as a kid with a chemistry set

)
Forgive my rash assumption of not being sent through the correct recovery physio process, but a few people had straight away said I was most probably going to need more physio than offered to me as standard.

I'm already feeling the injury settle down and not dependant on painkillers, instead only taking them when needed and Pre-emptive at night to make sure I get a full night's sleep.
With regards arm position in the crash, I don't even remember having the chance to naturally put my arms out to brace.. It seemed so instantaneous. I think I hit the ground straight on my left shoulder (with my head scraping along too from the looks of my lid, and I remember hitting it too). My glove on that arm was also ripped off my hand which confirms my arm was dragged as opposed to out in front.
When I think about it and notice all the other little cuts, etc. I realise I could easily have come out of it even worse.
