Thanks, Dr.
So I will keep my chin down when doing pushups and situps.
I neglected to tell you that about 1 month after this surgery I started with backaches, when I go for a walk, in those thick muscles that run along the spine, maybe it is the trap or the Rhomboideus major. It really feels like a backache that goes with the flu.
In any case, I am convinced that the original stenosis pain was triggered by pull ups and chin ups. I had managed to get up to about 12 each that I did faithfully everyday for a year. I came across a Marine major on the web who posted the same symptons as my own, before surgery, and the only thing we had in common was no stenosis symptons until we got serious with the pull and chin ups. Too bad because they are great exercises and I was about to start climbing rope. But I stay away from them now.
