I dont understand why I get pain in my chest. Its like someone is holding my heart and squeezing so tight, knocking the air right out of me. I cant breathe when this happens..Hurts to breathe.  I have a constant heaviness in my chest and I have a hard time breathing in and out.
Thanks for your question on Chat Doctor. I can understand your concern. Heaviness in chest, difficulty in taking breath in and out are commonly seen with heart diseases. So first get done ECG, 2d echo and stress test (trade mill test). If all these are normal then no need to worry about heart diseases. Sometimes undiagnosed stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. 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.  Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
