bigjim, just read your note again.
copied and pasted from another thread, cos I couldn't be arsed to type it out again!
I've had this, on and off for a few years. Never had a pain which I could find with my fnigers by pressing it, but it was a very localised, very sharp pain between vertabrae, feels as though it's in the muscle off to one side of the spine?
It was episodic; it would get to a stage where I'd think "I can't live with this any longer, I must see someone." but I'd wake up the next morning and the pain would have subsided a bit.
The pains/spasms became more frequent, more painful and longer lasting: once a month for a week or more. I went to A&E (Bad, I know, but it was out of hours and it felt like my neck was going to fall off), GP, sports massage therapist. Only got drugs and a "come back if it's not better in a week" from the NHS, which is really all I expect from them for this sort of thing. The sports massage therapist told me to go and see an osteopath or a chiropractor.
A friend recommended an osteopath in London. I saw him, he said I had a hyper-mobile neck and a very immobile upper spine, so all of the movement my head and shoulders needed was put through the same few vertebrae and the muscles around them.
I think cycling has something to do with this, your shoulders stay where they are in relation to the bars, an your neck does all the looking around.
I was blown away by the knowledge, skill and sensitivity of the osteopath, and the fact that I haven't had a single relapse in 4 years since my single vist to him.
Hope some of that helps!
Could be that an equally skilful chiro or physio could have sorted me out. Turns out this guy is very well regarded professionally, I've recommended him to friends who've had very successful treatment from him too.
He's been doing it a while, and I'm sure if he'd started his training in a different place, he'd have found his way to a similar understanding of the body and set of techniques that he uses as an osteopath.
