Key 📝trigger point is a point whose release also quiets satellite points elsewhere.
In 📝Trigger Point Therapy the practitioner looks for the point that, when it eases, takes other knots with it — often a central point whose referral zone had grown its own spots. That is a session strategy, not a diagnosis and not a promise that one hold will clear a whole chain. If satellites stay loud, they get their own dose.
Clients feel it as "you pressed there and the other place changed." Work still stays in a breathable range; chasing a key point past guarding loses the advantage.
