The second thing I would like to address is your symptoms like MND (Motor Neurone Disease). I suffered a progressive decline in physical ability, that at one point I wondered if it was ALS/MND, so I did study this in some detail but it’s a long time since I looked into these (10yrs), so forgive me if I’m wrong and please feel free to correct me. I believe it’s the back of the spinal cord that’s linked to these symptoms, yes ?
Well in Cranio-cervical instability, the spinal cord gets stretched and squashed when you move your head in various positions (the worse usually being flexion – so avoid this at all costs). Either of these two mechanisms can injure the spinal cord, sometimes temporarily (where you notice intermittent symptoms). I cannot stress strongly enough that you wear a fully supporting collar – the best I have found for cranio-cervical support and alignment, is the Philadelphia collar – trust me, no others come near it. I have been wearing mine nearly 10 years and it’s brought great improvement!
