Information Source

Most of the information here was adapted from Travell and Simons' Myofascial Pain and Dysfunction: The Trigger Point Manual (2-Volume Set).  If you have or treat people with chronic pain it is one of the best resources available. It contains much more than just quality trigger point drawings. It gives specific info (symptoms, related trigger points and treatment) for each muscle.

How to use these pages.

Begin by choosing the general area of pain from the menu at the left.  A figure will be shown that is used to locate the region of pain. Under that regional heading are listed the muscles that may refer pain to that area.

Muscles that are likely to refer an essential pain pattern to that area are shown like this:

essential pain pattern muscle

Regular type identifies the muscles that may refer spillover pattern to that area.

The muscle which is a more frequent cause of pain is listed higher.

How to read trigger point drawings

The X represents the trigger point & the red shaded area is the referred pain caused by the trigger point.

To find out if you have a trigger point

A trigger point can often be felt as a lump or can cause a twitch. To see if you have a trigger point push on the suspected spot.  If it is a trigger point it will be more tender or sting & the referred pain will increase.
