I was in a bicycling accident 12 years ago where I flew and landed on my head and
cracked my helmet in two, sustained a mild concussion
. I do a lot of sitting at the computer for my job, and have a history of disc issues in my lumbar spine. My neck has hurt, intermitently, on my right side, for as long as I can remember (more than 5 years).
The pain feels like a stiff/seized neck, I have headaches, pain goes across my right shoulder, down right scapula.
