tiff,
Its really impossible to tell you whats going on without more data. Your symptoms are somewhat nonspecific, but concerning enough that they warrant further work up. I suggest if you have another episode you seek out medical attention and schedule an appointment with your physician to further evaluate the surce of your symtoms.good luck
Also since about a year, I've been feeling a strong heartbeat. I am a 22 year old male. I run every other day (and do not feel it while I run). I can feel the strong beating when my heart beats slow and I am relaxed. The more I worry about it, the harder I feel it beat. Sometimes I don't because I don't think about it, but its almost always there... always. I have no other symptoms and am very healthy. I am a hypochondriac... but I can definately feel this heart beat and although I got used to it, it worries me constatnly. Doctor listened to my heart and all sounded normal. Good rhythm, no weird sounds. Blood tests came back normal. But I never went to a cardio. I am too scared to go and when I only start thinking about going, I can feel my heart pound. Often when it pounds, I also feel like an adrenaline feeling, like before a roller coaster. I think about it before I go to sleep. When I wake up, I can't feel it, then as soon as I think about it, I feel it beating. Please someone help, because I am going crazy from this pouding. My family is saying its all in my head, since I am a bad worrier. But I worry that it may be heart disease or something dangerous.
