I agree that he sure needs a good medical team to help him find out what's going on. It sounds like 'referred pain' but might be something else. Obviously I'm not a doctor. Here's a definition from Wikipedia...hope it helps.
From Wikipedia, the free encyclopedia
Referred pain (also reflective pain) is a term used to describe the phenomenon of pain perceived at a site adjacent to or at a distance from the site of an injury's origin. One of the best examples of this is during ischemia brought on by a myocardial infarction (heart attack) where pain is often felt in the neck, shoulders, and back rather than in the chest, the site of the injury. The International Association for the Study of Pain, as of 2001, has not officially defined the term; hence several authors have defined the term differently.
Physicians and scientists have known about referred pain since the late 1880s. Despite an increasing amount of literature on the subject, the mechanism of referred pain is unknown, although there are several theories.en.wikipedia.org/wiki/Referred_pain
