My back is fine now. I have four herniated discs in the lumber spine area which like to remind me of their presence every once in awhile with odd twinges or occasional stiffness but otherwise get forgotten about.

My back injury predates the sensorimotor concept but I read a few books by Dr. Sarno on back injuries at the time and decided to follow his concept of rethinking back pain and its origins. And not reduce movement further and further to rest my back. I did a lot of physical therapy and some acupuncture and basically otherwise tried to ignore the back pain unless it was severe. And that protocol helped me not "freeze" in anticipation of "more pain" everytime I had some pain. That is, the lessening of anticipation of more pain made a huge difference.

I recovered enough to skip the surgery two surgeons orthopedic surgeon said that I would have to have or otherwise end up in a wheelchair within a few years. That was 30 years ago and taught me something about trusting the body to accommodate to an injury and possibly find a workaround and a kind of new normal. It also taught me not to worry too much when two orthopedic surgeons give me bad news but to just do some research, not panic, maybe get a third opinion :-).
