[|Human|] I wake up in the morning with pain from my neck down my left arm and into the left side of my chest. I have been suffering from a painful left shoulder for some months and having physio for this it feels like a muscular type pain is this likely to be cardiac or neurology related
[|AI|]  Hi there.  The pain you describe can occur due to a cardiac disease but in such a case is usually associated with breathlessness, lightheadedness and is not specific to early mornings. For starters, you can get an ECG to see if it's abnormal.However, having said that I think in your case the pain is neurological and is probably due to a nerve getting entrapped in your cervical spine usually due to spondylosis of the cervical spine. Also changing the sleeping position may help. For the pain you need to get a X-ray of the cervical spine and if necessary use a soft cervical collar to relax your neck muscles. Hope this helps.
