I am having C 3-4, C 4-5, C 5-6 ACDF surgery on Dec 14th. I am a very active 53. I do kick boxing, zumba, weight training, walking and I am a belly dancer. I can not imagine not being able to work out? How long before I will be back to form? How much mobility can I expect? How do I deal with a collar for two months? ANY information is appreciated.
