Wondering if anyone else has experienced this. I started using a CPAP (APAP) about a month ago. Most nights I wake up around 4 AM with severe midback pain, seems to be radiating from T8 ish. This outside the normal AS pain, but similar (maybe a little higher up the spine) than a flare up before I started Humira. Unlike the "traditional" flare-ups, my days get better and more functional with heat, stretching - and being out of bed. Kind of a pick your poison issue. The threat of apnea related issues along with sleep deprivation versus nasty pain and ... sleep deprivation.
DX AS 2016. DX DISH Syndrome 2000. Humira, SOMA as needed, oils (black spruce, wintergreen, cypress, peppermint, lavender). Severely intolerant to NSAIDs.
