Shoulder and Rotator Cuff Pain

Trigger Points and Shoulder Pain

Shoulder pain is one of the most commonly misattributed pain conditions. Imaging often reveals structural changes, but trigger points in the rotator cuff and surrounding muscles are responsible for pain in many cases where no structural damage is present.

Primary Muscles Involved

The infraspinatus, subscapularis, supraspinatus, and deltoid are the primary trigger point sources for shoulder pain. The infraspinatus in particular refers pain to the front of the shoulder and down the arm in a pattern frequently confused with biceps tendinopathy or labral pathology.

Distinguishing Trigger Point Pain from Structural Injury

Trigger point-driven shoulder pain is typically diffuse, aching, and may shift or refer. It is often worse at rest or at night. Structural pain tends to be reproducible with specific movements and linked to loss of strength or instability.

Addressing It with the Pressure Pointer

Target the infraspinatus first as it is the most commonly involved. Reach the Pressure Pointer to the posterior shoulder blade and apply sustained pressure to the most tender points. Follow up with the deltoid and upper trapezius to address the full referral pattern.
