I've had issues for a few years now getting a good nights sleep. I don't wake up frequently during the night, I just feel as though my breaths are more like very shallow gasps as opposed to a normal breath. I noticed that this started happening after I began deadlifting. I know I have chronic tension around my t-spine and through the deep erector spinae. When I get in there with a baseball and really loosen it up, I feel like the rib cage can expand more to allow a deeper breath. This is temporary though as it will tighten up again some the next day. The issue for me is that even when I really loosen up those muscles, my poor breathing habits still persist. Almost as if they're so used to being in a chronically tight position that I don't even try to take a deeper breath. I was thinking perhaps its central sleep apnea. An overnight sleep test is over $3k though. Unfortunately I don't have this to spare at the moment. Should I continue with the soft tissue work in that area along with the ext. intercostals? Or should I just go ahead and purchase an auto CPAP machine?
