I gotta get this off my chest

I haven't told this to ANYONE but my husband. On Fathers Day, my husband, couple of friends and me took a nice 100 mile trip south of Atlanta. It was a great trip but it was my first time riding more than an hour.
The next morning when I woke up, my chest was really hurting, it was really tight. I took a couple of Advil and went to work. Well, the advil didn't work and my chest was hurting really bad. I was clutching my chest and it hurt to breath. My supervisor thought I was having a heart attack and called the base fire department (I work on a military installation). They took my vitals and decided I needed to go to the emergency room so they call the EMS guys and rush me to the near by hospital. In the EMS vehicle, they give me nitro glycerin and told me that if I was having a heart attack it will help but if I'm not, I will get a bad headache. Well, I didn't get the headache so everyone, including me assumed it was my heart. I get to the hospital and the doctors start to run all these test. EMS told them that the nitro glycerin didn't give me a headache. After 4 hours and alot of test, I realized that it wasn't my heart that was hurting but it was my chest muscles from the ride the day before. What's funny is the doctors were coming up with all these crazy theories on why the heart treatments they were doing was helping me but all the test showed that my heart was fine, no blockage (thank God) of any kind. I didn't have the heart

to tell them what was really wrong. After 12 hours in the hospital, they gave me pills to take and made an appointment to a heart specialist for me and sent me home. I didn't take the pills and cancelled the appointment.
My next long ride gave me chest pain the next morning. My third long ride was fine, by then, I had learned to relax my shoulders and body.
On a side note, everyone at work was really nice to me for a month. My supervisor still asks me how I'm doing and this happened in June
