1. The first lot of pictures i assume is you going from slouched sitting to sitting up straight. Does the pain after activity come on while slouched or when you sit up straight?
The pain comes from slouching TO sitting up, during the movement.
2. The second lot of pictures is very instructive. A further question would be - does the pain change (more/less/same) if you lift your leg up STRAIGHT then slouch over and put your chin on your chest? If so, it is nearly certain it is a neurological problem to do with the spinal cord having some scarring or tethering.
Pain is felt when i lift my leg straight then slouch and chin to chest yes.
And i would be so so cool if i got fixed over the internet.
If this was a spinal cord issue, would this be the reason i have over and under firing muscles?
Also is there anything more i can do to fix this?
