I am in my 60's now and had the type of surgery you are asking about many years ago.My surgery was done through the front of my neck.My problem was with the same area as you.I have to admit that if I had had it done much sooner, I would have had better results. However, the recovery went well. I had to wear a rigid collar at first, then a soft one. Recovery was a couple of months or less and was not really terrible. I still have some residual pain in my right arm above the elbo, but I think that this is because I did not have it donw earlier.Good luck to you. I have full use of both arms and the scar is barely visible. Good luck to you , :-)
