Because of chest pain, sweating, and gasping for air in the middle of the night, I’m scheduled for a sleep study. Has anyone noticed if there seems to be a connection between pain coming from the spine and symptoms of sleep apnea? I’ve noticed relief when I get an atlas adjustment from my Chiropractor, but it’s not permanent, and I have had for several years a lot of pain in my neck, shoulders, and between my shoulder blades that seems to radiate especially under my left arm to my left pectorals. Occasionally it includes my right pectorals. Cardiology tests 4 years ago revealed nothing, and pulmonology tests revealed COPD (non-smoker). If I’ve had sleep apnea for years, could that cause COPD? Could all be caused by neurological issues from the spine? Could it also be caused by GERD, which I might also have?
