When people try to improve their flexibility, they can go so far before pain prevents them from going further, not to mention of course that their muscles and tendons are close to the limits of what they can bear without being damaged. Over time, the more they stretch, the more flexible they get and the pain engages at a later and later point in the stretch. My pain is in my back and if I try to bend and touch my toes I can get my hands to about halfway between my knees and my toes before the pain in my back prevents me from going any further. This pain will turn on if I make a 'wrong move' like a sudden bend or moving a leg the wrong way when sitting or lying down. I used to be able to touch the floor and curl my fingers under my toes, even while I had a bad back. I've not done any stretching or other exercises that I used to do purely to help my back. But I'm wondering whether, if I tried stretching and improving my flexibility so pain didn't kick in when I made a movement that impinged on (what I assume) are tight tendons or nerves in my back, wouldn't that be a good thing? As I see it there are two types of back pain that I experience. The pain I get when I'm sitting and stationary, which seems to increase the longer I sit. I believe this is definitely TMS pain. Plus, the fact that it's moved to the front of my legs which I never used to have before starting this road to recovery is more evidence that it's TMS. But then there's the pain that's turned on when I make a movement that pushes my lack of flexibility to the limit. I'm wondering can't I try and improve this by stretching without threatening the belief that pain in my back is largely caused by TMS? Couldn't this be in the same league as someone practicing stretching every day so that they could eventually do the splits without pain? What I'm worried about is compromising the belief in my brain that TMS pain is caused by emotional and psychological issues - because I know how important it is to have this belief for a recovery. I've been meditating on Dr Sarno's 12 Daily reminders and when I get to No.12 "I must think psychological at all times, not physical" I have a feeling of guilt that I'm not doing this when I get that sharp pain from a sudden movement. It just feels so much more physical than the passive pain I get from sitting in a chair. I'm happy to be talked out of this and continue not to do stretching associated with bad backs. It's just that this has been playing on my mind for a while now.
