The Failed Loop

You're pulling your arm across your chest and stretching your rotator cuff daily, yet reaching behind your back or overhead feels like hitting a solid bone wall.

The Hidden Bottleneck

The Subscapularis muscle — sitting flat on the front of your shoulder blade deep beneath the armpit — is heavily adhered to the rib cage tissue. It physically locks your humerus in internal rotation, preventing the natural outward glide required for overhead movement.

IVThe Targeted Resolution

Specialized manual access to the subscapular space at Break On Through Massage Therapy to release deep anterior glenohumeral adhesions, restoring immediate rotational range without painful forcing.

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

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.

The Secret Reason Your Shoulder Pinches When Reaching Overhead

Your posterior rotator cuff (Infraspinatus and Teres Minor) has developed dense fibrotic adhesions. When you lift the arm, those muscles fail to lengthen eccentrically — which prevents the humeral head from dropping down smoothly, so it smashes upward into the acromion gateway.
