Numerous massage therapists - some of them quite good - have commented that my erector spinae (in the area where my lumbar/thoracic spine meet) are “hypertonic,” which I understand to mean they are over-active.
Sometimes I do feel a little unstable there. And over the years, I’ve experienced a sudden twinge in that general area when doing something really grueling like, say, bending down to tie my shoelaces
I also found that it frequently followed from tight hammies/psoas.
Anyone else have this issue? Any suggestions? Insight? Thanks!
