About six months ago, I was diagnosed with having bulged a disc in my neck. For several months I could not move my neck at all due to the pain. After much physio, my neck is 95% now pain free, and range of motion is good.
However, the muscles in the back of my head - at the bottom of my skull where my head meets my neck (used in nodding), and on the left and right sides where the two big neck muscles connect to my head (used for looking left and right) - are still extremely stiff. When I twist my head, I often hear a crunching and popping (like a muscle knot releasing). Again, this is in my head and not my neck. Here is a rough diagram of with the main areas of stiffness highlighted: http://s8.postimage.org/5nadcw52d/back_of_head.png
This crazy tension makes me feel like I cannot comfortably look left and right - I can, but there is pain where the muscle refuses to go any further, and makes simple stuff like looking left and right to cross the road or looking in one direction for any length of time difficult because the muscle just wants to pull back to centre.
I stretch my neck several times every day (rotation, flexing, chin tuck, etc.) and my physio has attempted acupuncture several times without success, and I don't know what to do any more. Again, my neck isn't the problem and this doesn't feel like a tension headache... more like bunches of really tight muscles and knots that refuse to release and let me turn my head naturally and freely.
Sorry for the long post, but I wanted to be as clear as I could. If anyone has any help or suggestions for what I can do, I would be incredibly grateful.
