|Trigger Point Map
|Muscles both produce and accumulate waste products. The more a muscle is used, the more waste
material it produces. Repetitive use of certain muscles will ultimately cause an accumulation of waste
products -- this creates trigger points. Trigger points cause tenderness, restrict normal range of motion,
limit muscle flexibility, weaken the muscle, and may refer pain to other parts of the body.
The referral of pain can lead to symptoms in areas far away from the trigger point. The referral of pain
does not follow nerve pathways, and may sometimes be in a muscle far away from the trigger point. A
good understanding of trigger points and where they refer pain may shed light on pain conditions that
appear to be unexplainable.
Below are several maps of trigger points for the upper back. Keep in mind that trigger points can form in
any muscle in the body -- they are not limitted to the upper back.
