Our wise body glues things together to keep them from moving and causing further harm.
A living cast.
Similar to the body creating a fever to kill germs invading, this cast has a purpose and a duration.
I can break through the body's defense and restore mobility.
But what if the injury has not yet had time to heal yet?
Restoring mobility prematurely may re-injure the body or at least keep it from healing thoroughly.
There is a timing to all things. A living cast can become permanent and a fever can become so high the brain bakes. Sometimes interventions are needed. The delicate task requiring wisdom and skill is to gauge the timing correctly. Let the body do what it does best. Step in rarely with a small tweak. Best to fix small things consistently to keep things even within the body.
