Does anybody have any knowledge of adverse neural tension? Clemson? Flash?
The reason I ask is that at the moment I have bilateral hamstring and achilles tightness, the left is worse, and I also have a tight left lower back.
The reason I am ?ing neural tightness is that if i stretch forward to touch my toes the tightness is released, slump nerve stretching/mobilising also seems to help.
I may have answered my own question! 
I just want to know if im on the right track.
Cheers
