I had a night. Went to the ER because I was having chest pains that lasted what felt like at least 5 minutes, and my left arm was tingling (I’m fine now, they couldn’t find anything wrong with me). I learn that they advanced a few things since I was last there (like how X-rays no longer require lead aprons and how instead of looking for veins for each IV shot or taking blood, they insert a small tube into a vein and use that throughout the visit for both).
