I had my collar bone plated about 2 years ago. It felt sore for one or weeks but I could move it slowly without too much trouble, much much better than when it was not plated. I think I was told not to move it at all and keep it in the sling for first couple weeks so didn’t move it but could if I wanted.
I think physio allowed some movement after that and possibly full range after 6 weeks. Although that was without any weight or strain on the shoulder. I could get on with everyday stuff after 4 to 6 weeks. I think it was probably 10 weeks before I could start to do any real exercise and about 14 weeks before I was given free reign and allowed to cycle again.
Took a couple of years before I had full feeling in that area again.
Took about a year before I got most the feeling back, its still not fully there but not too bad. In the early days I used stand in front of the mirror poking it with my other hand. It was a weird sensation because the finger could feel it was touching something but the shoulder didn’t feel anything. Its weird feeling when you can’t feel your own body touching it self.
