OK - almost 1 week into using an APAP with nasal mask. One feature I've found with the higher pressures that kick in on the APAP is that I breathe with a greater inflation & deflation than I would normally have done before - not saying it's a problem as shallow to non-breaths was the main reason for me checking this out in the first place. But the issue is that after about 4-5 hours I get pains across my chest - they're external, muscular strains across the upper rib cage. Has anyone else experienced this? Is it "normal" and expected at the start of a new way for your body to breathe?
