Dear SigMik
I agree with you Sigmik, for one his age puts him in the category of people who tend to have disc problems, and the positive half of the slump test suggests so, i however doubt if this disc is fully herniated by virtue of the anatomy of the thoracic vertebrae (limited space within) and disc issues are less likely (not to say they dont happen). Perhaps the disc is herniated centrally and pushing on posterior structures (i.e) the dura matter...this would support the multisegmental referral pattern he gets (pain moving up his neck) when he adds the rotation. The non capsular presentation he gets now also supports a discy hypothesis...
Dear Dekkly, I definitely agree with my colleague, you probably have a disc problem...may be cause by torn ligaments supporting the vertebrae/ or by virtue of age your spine and previous sporting life your spine was prone to trauma weakened by denegeration, considering you might be arthritic in places u dont know about ....
Fill us in on the results of the slump test as suggested by SigMik...also can you tell us what the chiropractor did for this problem? Just wondering why you havent gotten any joy from Chiro..
Cheers
