Hi Carly... You are not going mad. Something is happening with your body, it just doesn't have a name yet. At the age of 45 I went through something similar. I was experiencing symptoms that led me to believe I had a heart condition. I went to my family Dr and told him and he ordered a stress test. I passed it with flying colors. So it was believed that all was alright and life went on. The symptoms never went away and picked up in frequency and intensity. A few months later I ended up in the emergency room with what *they* diagnosed as an angina attack. Went back to my Dr again and he sent me to a cardiologist. I had another stress test which I passed. The symptoms were still presenting themselves and I told the cardiologist. He said not to worry about it and to "stop dwelling on it". He did tell me if it would make me feel better he would order a heart catherization to alieviate my fears but he was sure I was fine. He felt I was too young to have a problem and in too good of shape, and... a woman. I went home and thought about it and called back and told him I wanted the heart cath. It was performed the following week and he found one blockage and put a stent in. I continued to have symptoms and called the cardiologist to tell him. His receptionist reassured me that everything was alright, they had found my problem and taken care of it and told me that he was on vacation and wouldn't be able to see me for 3 weeks, that was the earliest next open appointment. I hung up and decided the next time I had a problem I was going to travel the 50 miles to the nearest city that had a heart center. The following week I had another bad night and my husband drove me to one of the major heart centers 50 miles away. They admitted me on a Saturday evening and on Monday performed another heart cath and found 4 major blockages and a 5th that wasn't very bad. I had open heart surgery the following week. Four bypasses and another stent. Carly, for a while I thought I was going mad too. It was a battle getting the Dr to listen to me. He was just sure that I was fine and that I was imaging the symptoms. Thank goodness I knew better and didn't stop until I found a Dr that would listen. Carly, if you feel you are having a heart related issue don't stop. This is your life and not the Dr's. Find a Dr that will listen and will perform whatever tests are necessary to give a name to whatever it is that is ailing you. I did and I am happy I did. Had I just taken the word of my first cardiologist that everything was fine, I would be dead right now. I am not saying that your cardiologist is not a good Dr but I for one do not trust stress tests. They may be a sufficient first step but they are not infallable. They don't always tell the full story. Sorry for the book but I wanted to give details so that you would get the point I was trying to make.
