I had a bit of a health scare this morning.
Last evening, I woke up with a pain in my chest. My pulse was still strong, and my arms weren't numb or tingly, so I took it as a muscle cramp and went on to work. It even seemed to be getting better after a while, but after a few hours, it came back with a vengeance. I suffered through it during my shift at work, but I stopped off at the emergency room on the way home to get it checked.
(BTW, if you want to be seen in the emergency room immediately, complain about chest pains. I swear, I was in a bed surrounded by nurses and wired up to an EKG in less than a minute.)
Well, after running every test they could find (EKG, blood work, X-rays, the whole shebang), they found... nothing. It's not my heart, it's not a broken rib, it's not an embolism, it's nothing they could find. It's likely a pulled muscle, or maybe gas. The doctor suggested I take some ibuprofen, but prescribed some industrial-strength Pepto-Bismol just to be safe.
