greetings friend, degenerative disc disease
in the neck and lower back often comes with normal aging and should not involve difficulty with breathing or chest tightness
, if you feel like you're going to collapse upon standing, this could suggest a cardiac or respiratory or blood pressure issue that he should go to a regular doctor rather than to the emergency room. My concern is that something is going on besides the degenerative disc disease that needs to be addressed. have a great day.
