Was at the gym this morning doing my cardio workout when something unusual happened. I usually do 20 minutes at my target heart rate of 153. Normally, I can keep it above that with no problems. Today however, was a different story. As soon as my heart rate would climb above 150, I would have sharp pains in my chest. When my heart rate dropped, the pain would go away. After the second time, I thought it was time to get off the machine. As I was leaving the gym, it was no longer hurting. I assume because my heart rate was back to normal. So I went on to work like any other day. Throughout the day, every time I would do something strenuous, the sharp pain would come back. Nothing like you see when someone has a heart attack, and their grabbing their chest as though it were gonna jump out and run away. Just a bit of a nuisance. By the time I got off work at 6:30, the pain was still coming and going. I called the nurseline that our company has and talked to one of the nurses. She asked a bunch of questions and I answered honestly. She advised me to seek medical attention IMMEDIATELY because it could be cardio related. So off to the ER I went. When I went in and told them I had been experiencing mild chest pain, they pretty much rushed me into the back and immediately started hooking me up to a bunch of machines. They ran an EKG to see what was going on. For how little pain I was in, this sure was alot of fuss. I expected questions like "how much does it hurt on a scale of 10" first. Anyway, 3 hours later I am released with a diagnosis. My heart is fine, but the muscles around it are what's giving me problems. I'm to take it easy ( no gym ) for atleast a week and take ibuprofen. Man, what a night. It seems weird to just write off these chest pains as "nothing to worry about". Every part of me wants to say, "But it's always bad to feel pain in that part of the chest." But, they are one of the top heart hospitals in the country so I trust 'em. All right, I'm going to bed now.
