Last 3 days every so often my heart will beat like normal but will feel as if it pauses between beats for longer then ussual with a beat slightly stronger and then it resumes beating normally. Everyone once in a wall I'll feel like a flutter or what I mentioned above but it is never constantly happening. I take adderall for adhd and even before I started the adderall again after recently having a baby inwhich I was off it for 9 months I still every once in a while have fluttering etc. that goes away in a day or two, sometimes after a few days or less then a day, there is never a constant pattern and there's no other symptoms. Should I be worried and what is going on??? What could be causing this??? Stress??? Not eating and/or drinking enough during the day??? Fatigue??? Coffee???

Other concern is chest pain that sometimes happens but it's always more to one side or the other and there's no other symptoms but I worry at times if it could be a heart attack??? One time I did go to the ER and everything looked normal, EKG and blood pressure was normal, heart wasn't enlarged and everytime I have gone to the doctor, recently more often I never had anything near high blood pressure and don't have any rapid heart beats during the chest pain so I'm wondering if it probably isn't heart related but something else??? The pain at times may even last and be there for a long time but that's all it is, just there no dizziness, fainting, rapid heart rate, or high blood pressure so should I worry about a heart attack occuring??? I wonder if anxiety which I get at times, cause the chest pain???
