I had a neck fusion on my C2/C3 about 7 years ago and have never done any preventative maintenance since my surgery. I am a very active guy, and I mostly road bike and whitewater kayak for exercise. Recently, I played basketball a couple of times and my neck started bothering me as a result of that activity. My question is, what exercises are good for my condition and what additional steps would someone take to help prevent future neck issues? (i.e Yoga, computer screen height at work, sleeping on back, etc.)
Also, what activities do I need to avoid?
