The Failed Loop

You do overhead door-frame stretches and roll your upper back on foam rollers, yet you feel a constant deep, bound tightness right behind your shoulder blade every time you sit at your desk.

The Hidden Bottleneck

Teres Major is the lat's little helper. From repetitive reaching or desk slouching, the fascial sheaths of Teres Major and Latissimus Dorsi develop severe cross-linking adhesions — effectively gluing your armpit musculature shut.

IVThe Targeted Resolution

Specific clinical manual pinning with active movement to shear the Teres Major layer away from the Latissimus Dorsi, restoring fluid independent sliding of the upper back muscles.

The Front-Wall Lockout: The Deep Shoulder Muscle That Feels Frozen

Waking Up with Numb Fingers? It's Likely a Neck Bottleneck, Not Carpal Tunnel

The brachial plexus is getting mechanically pinned further up the chain — specifically through the anterior and middle scalene muscles or beneath pectoralis minor. That structural bottleneck cuts off nerve conduction at rest.

The Forearm Trap Mimicking True Carpal Tunnel

The median nerve passes directly between the two heads of the Pronator Teres in the upper forearm. When that muscle becomes fibrous and chronically tight from repetitive gripping, it physically pinches the nerve — perfectly mimicking true carpal tunnel.
