I am 21 male, about 320 lbs. I get a sudden thump in my chest with a small squeeze, and I get out of breath. It usually lasts 1-3 seconds but its really scary, I usually reach for my chest when it happens. It can occur at any time, but I noticed when I am more active it happens more frequent. It occurs often when I bend down to pick up something.It can happen twice a day, or once a month. I went to the doctor and he took a echo cardiograph of my heart, and it came out good. I do suffer from anxiety and have been under a lot of stress lately.
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about heart diseases as your echocardiography of the heart is normal. In my opinion, your symptoms are mostly due to uncontrolled stress, anxiety and panic disorder. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Counselling along with anxiolytic
