Has anyone ever had arthritis in the neck? Or know anything about it? - arthritis in the neck more condition_symptoms

My good friend, discovered that he suffers from arthritis in his neck, and you are sure that is what is causing your back pain of others. Have they now operate. I researched and I thought they would be replaced and make a disc done in the arthritis. I know it is an intensive operation, but I wonder how much? and how long does it take to heal after?
