The turkey neck is from edema buildup from the lymphatic system damage or, I suppose, it could happen from surgery. It resolves but takes a while and lymphatic drain massage will help it get the big bulge quickly but not resolve it completely, in my case.

Don, is the "tightness" from a surgical scars! Does it feel like your sternocleidomastoid muscle doing a slow contraction? The contraction part is a good thing to indicate more stretching to get some blood flowing. Eventually, the muscles that do the slow contracting and alternating with instant cramps that creat big, painful knots are the muscles that atrophied first for me. Mine kept getting smaller till they turned to cords or strands with no elasticity left. With 18 months of hard work, I have been able to "revive" sections of the muscle.
