Linda, In trying to be a little more specific, I have mentioned scar tissue related, but I have had my large anterior procedure that does not grip or cause pain....so, its back side only, in the hardware zone. It seems to squash the scar tissue assumption. I have no gripping or pain from my front procedure.
Now I wonder if it could be a biofilm related occurrence since the gripping is only in the hardware zone. Are we constantly fighting bacteria, or some sort of metallic soft tissue reaction even if it is on a small level? I wonder if this is what is causing fatigue? Are any of the younger scolis experiencing fatigue years later after their surgeries? The only ones that would see this would be the surgeons upon revision, but usually only if something is drastically wrong....not in a mild case.
Another thing is that the bear traps usually happen in the throacic between the shoulder blades, and not so much in the lumbar. The lumbar planks that Susan has, I have only felt a few times.....(lumbar planks feel like a 2x4 in our lumbar area in varying degrees of stiffness) Several members have reported this here in the past.
I also have zero pain with my huge pelvic anchors. (Which are buried in bone) This leads me to believe that it narrows it down to soft tissue and not a reaction to screws being buried in bone.
This is also not a nerve pain.....its a gripping, tiring, sensation.....
The article below explains about the future of biologic coatings, antibiotic coatings, BMP coatings etc in hardware.....A very interesting article...
