Thanks for your question on Healthcare Magic.
I can understand your concern.
Since you are young (25years old), possibility of stress and anxiety related chest pain is more.
But at the same time you are having
hypertension,
tachycardia and worsening symptoms with anger, so we should first rule out heart diseases like angina or coronary artery disease (CAD).
So get done ecg, 2d echo and
stress test (trade mill test).
If all these are normal then no need to worry for major heart related diseases.
Your all symptoms are mostly due to stress and anxiety.. So
consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on it's solution. Do
anger management. You may need anxiolytic and other supportive drugs.
Don't worry, with proper treatment, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
