Iam confused about the cause of mine, i fell down some stairs awkwardly about 6 months prior to my symptoms....suffering no bad pain afterwards but my neck did go backwards.

I was working in an office which involed all day long computer use - i think possibly that a combination of the fall and the computer caused it (my posture wasnt great - used to perch on the edge of my chair a LOT)...im seeing who is think is the only UK TOS specialist in a few weeks so perhaps he'llbe able to give his view on it!
