I am 25 years old male from India. I have been constantly experiencing the fear of having a heart attack. I can even observe all the related symptoms like pain in left side of the chest, stomach discomfort (specifically on the right abdomen), pain in the left hand (sometimes left foot also) etc. I have been suffering from this for almost a year now. Last year I had my ECG done by an MD which came back absolutely normal and doctor concluded that it's nothing but anxiety. But still that fear and symptoms don't go away. I am very much disturbed and can't concentrate on my routine work. Am I really suffering from heart problem or it's just anxiety?
