My worst asthma attack to date at 5am and I was in the ER from 5:50 to 4 something. Was worried for a bit there they’d keep me overnight. They did a chest and throat X-Ray, a CT scan, a breathing treatment, tested me negative for Covid, negative for strep, tested my thyroid, tested for blood clots among other things. Then held me a while since my heart rate wouldn’t go down. Finally released me with encouragement I go to a cardiologist
