I have shortness of breath, strong heart beat in my chest, and increased pressure in my sinuses and head area. When I drink water it seems to  cool my chest and I am better when resting. I went to a doctor. had an ekg and chest exray and they did not see anything wrong.
Thanks for your question on Chat Doctor. I can understand your concern. First no need to worry about major heart and lung diseases as your reports are normal. Shortness of breath, palpitations, headache etc. are also seen with stress and anxiety. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You will also need anxiolytic Chat Doctor.  Don't worry, you will be alright with counseling and
