Finally went to the doctors, they want me on a longer dose of prednisone with a taper, they think it's a exacerbation due to a viral cold. My oxygen saturation level was 94-96%, which prior to all this, I was 99-100. They are sending a reminder to the respirologist to get me in ASAP. So does asthma lower oxygen saturation? They upped my symbicort to 3x daily instead of twice with my rescue inhaler.
