Re what happened at the chiro:
OK it's a little hard to remember exactly - he wasn't a great communicator and never proferred any diagnosis of my condition. He appeared to being lots of tests with raising very legs/arms etc but really don't remember the slump test and if I did it then there was no pain. Perhaps it's because my back went into one of it's very sore periods yesterday morning after I bent over in the shower - I heard a little click and then it got very sore. The evening before after circuit training it felt very stiff/sore and the click in the shower seemed to just do it completely. Maybe when I went to the chiro the condition was just there but dormant - maybe if I went again and passed on all the excellent feedback on here it would help? I do remember him using a special implement - it was like a test tube with a rubber bung on the end and it somehow used air pressure to push the bung at speed onto part of the spine - I have probably described this very badly! He made me lie on my back with my left arm over my rights houlder and me left knee up and did something quickly that made my back click and was quite sore. He gave me ultrasound and a heat rub. I stopped going because he just seemed to be doing the same thing each week without explaining what he was trying to achieve or what he thought was the cause. The last thing he mentioned was to bring in my running shoes if it was still no better (not sure why?) I must say I have always been sceptical of chiros and the constant expense without clear explanations of how many more sessions where needed - what we trying to resolve etc put me off. I have heard this about chiros before.
So let me know if the slump test was conclusive or whether I need to repeat it again with my wife - do the findings fit in with what you were expecting?
