The reason for asking this is because whilst when my pain has flared up it generally feels non specific and effects my left lower back, hip and back on a day to day basic I pretty much always feel a sensation in my lower back that just doesn't feel right. It isn't painful but it is located around the left side of my SI Joint and it therefore ties in with the nocebo that was planted by the osteopath I saw a couple of years ago. I've noticed that what generally happens is that when I make a movement that causes the sensation in a split second it is like an alarm goes off which sends a message to my brain that is basically screaming 'this is structural'. this all happens so quick that it's very hard to stop this obviously conditioned response. Whilst I can see the conditioning at work and how this fits in with the TMS theory I am finding it quite hard to move past the fact that the sensation feels so physical...it's almost like pulling/tweaking sensation and like I say it is never painful but it just pulls me into the structural though pattern. Obviously something is causing this sensation and it is very hard to see it as any other than a structural dysfunction or alignment issue. I'm wondering if a feeling like this that is so location and movement specific can still be part of TMS? It is frustrating as whilst this sensation is annoying on a day to day basis it isn't painful but it pretty much always leads to a flare up of quite an intense period of pain. I know from that sensation I am generating fear but it's hard to look past the structural explanation that my pain pattern is background discomfort, inflammation, pain flare up, inflammation reduces, background pain and then rinse and repeat...of course I know constantly being stuck in this pain explanation is going to just keep on giving me more pain but its like from the tiny acorn of the mild sensation and large oak tree is growing. Thanks for reading guys and any advice or comments are greatly received.
