Referred Pain Patterns

Side Referred Pain Patterns

Trigger Points in the Serratus Anterior muscle typically refer pain to the side and the lower portion of the shoulder blade.  Although the pain distribution isnít large, the pain itself can be very uncomfortable.  When Trigger Points are present in this muscle, breathing in causes a sharp pain in the side.  Some people also describe feeling unable to breathe out fully.

The pain of Serratus Anterior Trigger Points can mimic the pain of lung disease and heart attacks.  Although these symptoms should be taken seriously, if no lung or heart problems have been found, it is worthwhile to address these Trigger Points with the Pressure Pointer.
