I'd read this once, hurriedly, last month, but the second, in-depth look at it sinks in, Anamichel. What you've done and adjusted to is a kind of organic mind-body awakening few accomplish. I've seen the cup marks several times in IG posts without remarking, knowing you'd addressed some serious issue. Along with the sciatica and lumbar, to have the shoulders too and to work on getting this, and cervical vertibrae/disks and posture aligned (everything short of knocking a shoulder against a wall...eke!), deserves silent roar, of support.
