• This page contains information about muscle (myofascial) pain in the Chest and Abdomen region. It would be impossible to describe each and every muscle in detail, so I have therefore concentrated on the common ones.
• Please look at About Muscle Pain, Trigger Point Treatments, and About Botox, and Exercises for more information.
• Please note - in the diagrams below:-
  • X = the position of the trigger point (TP).
  • = the position where the referred pain is felt.
