No. I don't even know if that is a real diagnosis, other than describing "the where" and "what type" of pain you have.

You may be thinking of "complex regional pain syndrome" (two types) aka RSD, and this is definitely not "rhomboid and trapezius regional muscular pain".

More than likely your doc is describing a myofascial type of pain pattern, and this by no means identifies the cause and really isn't much to go on, other than inferring cause by where the pain is centered, and tracking back by pain referral patterns (see dermatomes).

Best of luck.
