Hi Marj, thanx for the reply. When I do the slump test and raise my head it eases the pain/discomfort - the same if I move my foot/toes pointing away from my body/head - does this fit in with your theory? I'm seeing my physio in about 45mins so I'll mention this to him. He had mentioned in the initial assessment something about the joint, and did a little work on it using, for want of a better word, a spring-loaded hammer.
