I had ACDF at C5/C6 in February 2009. I now have pain/burning in my upper back/right shoulder, and various sharp pains in my hands. My surgeon sent me to a PT to learn McKenzie "therapy". I'm supposed to move my head straight back while pushing on my chin, and also bend my head backwards. I'm supposed to do 10 or 20 repetitions, ideally every hour. I would like to hear from anyone who has used this treatment method after having ACDF. Did it help you? Thanks.
