Anyone, who had this surgery? I could not find any reference at all. I am planning to undergo one unfortunately, due to my n. accessorius damage. I am 20 y old and still want to do sports etc... this damage makes a lot of things impossible for me.

How's your recovery?
After months of the surgery is there any pain?
How strong the muscles are?
Is there any disadvantage?

Sorry for my bad English and thank you very much for your help.
