Thanks to all that have answered my questions so far.

I got the results from my brach. MRI on Friday - everything is looking pretty normal so this has ruled out TOS for me (although I still have rock solid scalenes for no apparent reason).

It confirmed mild prominence of the C7 transverse processes (as seen on an x-ray too) but no evidence of cervical ribs or calcified bands etc. Also states mild symmetric prominence of the cervical nerve root sheaths at each level but states this can be a common finding and no need for concern as no nerve root thickening etc.

So, you knowledgable lot, does this totally rule out the C7s being any kind of problem?

I have been advised by the neuro to see an anaesthetist to try and have diagnostic nerve blocks to see if we can isolate where the problem is coming from in terms of nerve disturbance - could it still be the C7 causing something like Occipital Neuralgia or would that be located elsewhere?

Thanks again everyone,
CindyCB
