should see your doctor immediately. Only after your
doctor has ruled out any Cardiac involvement should

of Chest Pain
in the chest and neck muscle groups can cause pain
that is experienced in the chest region. Typically
these muscle groups are overloaded by starting a
new exercise program or heavy physical labor.
Additionally, various sleeping positions can
activate trigger points in these muscles. Besides
pain, these trigger points may produces symptoms
such as breast tenderness and cardiac arrhythmia.
Muscles and Trigger Points that Cause Chest
The three muscle
groups that can contain trigger points that refer
pain to the chest region are:
The Pectoralis Major
The Pectoralis Minor
muscle group is the large, flat muscles found in
the upper chest region. The muscle has four
overlapping sections that attach to the ribs,
collarbone, chest bone, and upper arm bone at the
shoulder. This muscle group contracts as you push
with your arms in front of you (e.i. the bench
press) and when you rotate your arms inward towards
your trunk. The Pectoralis Major can contain up to
five different trigger points that refer pain in
the chest, shoulder, and breast regions.
Additionally, pain or numbness may radiate down the
inside of the arm and into the fingers. Trigger
points in this muscle group tend to activate
trigger points in the upper back muscles that
produce pain between the shoulder blades.
muscle is a small muscle that lies underneath the
larger Pectoralis Major muscle group. This muscle
attaches to the Shoulder Blade behind the collar
bone, and runs downward to attach to the upper ribs
in the front of the upper body. This muscle can
contain two trigger points that refer pain over the
chest and shoulder regions, and sometimes the pain
may extend down the inside of the arm.
muscle group is found deep in the lower neck. It
flexes the neck to the side and helps to lift the
rib cage when you inhale sharply. Trigger points in
the Scalene muscles can produce strong pain in the
chest, shoulder, and shoulder blade regions. The
referred pain to the chest occurs in a two
finger-like projection below the collar bone. Learn
