Thanks for your question on Chat Doctor. I can understand your concern. Most common cause for these symptoms is stress and anxiety. But better to rule out cardiac causes (hypertension, arrhythmia) and hyperthyroidism first. So get done blood pressure monitoring, ECG, 2d echo, stress test and Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about heart diseases. Also get done thyroid function test to rule out hyperthyroidism. 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. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
