More x-rays yesterday and booked back in for two weeks time for more of the same.
The good news, healing extremely well and they've removed the body brace from the collar as it's no longer required, so I was sent home in just the neck brace

I will be able to remove the collar when I'm at home to get the neck working again, it's rather painful looking left and right but I guess that's what happens when can't move your head for five weeks.
Ribs and sternum seem to be healing Ok, no concerns there so I've not needed to flag these with the hospital.
I'll give an update when I have more on the collarbone which should be Tuesday as that still gives the most amount of pain/discomfort, having said that I'm still bruised so that could also be playing a part in it.
