Not to be an alarmist, but have you had this checked out? I had years of neck issues too and was recently diagnosed with two collapsed disks, huge arthritic spurs that were compressing my spinal cord. The numbness and weakness in my arm finally conviced me to see a doc. In December I had major surgery where they replaced two discs (with bone from my hip), shaved off the spurs and fused the whole thing. It has been quite an ordeal - by the time I got into surgery, one disk had impaled itself onto my spinal cord and it took the doc 45 minutes to pull it out.

I, like you, figured it was years of cycling, computer stuff, etc. Turned out to be much much worse.
