With back now flaring up, Colts say Manning doubtful for opener

I would imagine that his neck problems could cause back soreness. In my experience, although I am not a doctor, I have just seen a ton, my neck problems have caused shoulder and back problems as well as migraines. I wish I could afford his specialists and surgeons. Heck, I would just take the surgery right now.

I wish him well. Nothing fun about spinal issues.
