AB, your situation is well known to all of us who had the surgery and all we can tell you is that you need to be patient, time will mend everything, try to be very careful and not to lift weight for at least 2.5 months, there are cases that the plate broke just because the person lifted excessive weight, that's a very unfortunate outcome but it is up to you to protect yourself. there are two kinds of numbness, one is along the scar, this will go away in few moths, for sure, it has happened to me, it has happened to bsbs, don't worry about it, it is annoying, I know, but it will go away. This is the kind of numbness you describe. There is a second type of numbness, it does not happen to all though, this kind of numbness has to do with the impact during the crash. It usually affects the Anterior Deltoids muscles because this is the point of impact. This kind of numbness affected me and it took me about 16 months to disappear. Of course it does not happen to others, it happened to me because my crash was very severe and those muscles, the tissue not the entire muscle, atrophied for some time. So all kind of numbness will go away with time too. As you understand there is no much to do apart from protecting yourself from a fall or other accidents or people who might push against your shoulder accidentally. In fact you must change the way you move a little, be careful as you walk, the doors and everything that comes near to you. Make slower moves and keep always in mind that you are not suppose to use your affected arm. I kept mine in a sling for at least 6-8 weeks when I was out or in a crowded place just to make other people see that I am injured and that I need special care. even at home I used the sling because it was more comfortable and restricted me from using my arm. and YES "The scapula just overcompensates the movement of the shoulder. So it's normal stiffness I guess." and YES it is normal and it has happened to all of us. But there is nothing wrong with your scapula. The surrounding muscles work a little more and this makes them feel awkward. ask more questions if you want!
