Other than coronary, what can cause pain in mid chest and neck and mid back ?

Several issues: Many things can cause chest pains-certainly cardiac the more important to rule out...That being said, arthritis in the back (t-4 innervated the cardiac area-so arthritis in the spine at that level can cause referred pain), reflux diseasse (heart burn-pyrosis), anxiety, esophogitis, gastritis, costochondritis, lymes, rheumatoid, etc. Are other possible causes. Get eval to determine your cause.

Several things: The most serious is thoracic aortic dissection. Less serious: cervical spondylitis can do all 3 simultaneously. A combination of GI or arthritic chest pains and shoulder bursitis, tendinitis, or arthritis can also do it
