I started on CPAP for OSA six days ago...first three days went well...fourth day had SOB after removing mask, which did not go away with one night off CPAP. Tried CPAP again last night...SOB still. Any ideas? (Have HTN, well-controlled, mild kidney disfunction ?IgA nepropathy, use Losatren, Crestor QAM and Claritin HS)
