Burning intermittent pain in left shoulderblade and shoulder for almost 1 year.cannot reproduce pain.fear angina or cardiac. pcp says not heart.ideas?

If your doctor: cannot figure out cause on full exam, it is probably nothing. It could be pinched nerve or pulled muscle. But it would be impossible to figure out in a forum such as this one.

Cervical cause?: Pain in this shoulder blade area is frequently caused by a problem in the lower cervical spine. Very classic referral pattern from the C5/6 facet joint and lower. Can also be from an upper thoracic disc herniation. Myofascial trigger point too. Bottom line is that you need to see a Physiatrist (physical medicine and rehab specialist) or other interventional spine specialist that sees this stuff.
