I ended up going to the ER this morning. I tested positive for influenza and they started me on tamiflu. My oxygen sats were low for me (86%), I was tachy, and I couldn't get my fever to come down at home.
I'm really glad I went in. It took multiple nurses with the ultrasound to get an IV in, but after some fluids and pain relief I'm feeling better. I got to spend some quality time on an EKG, too.
Take the flu seriously this year! It's bad stuff.
