Thanks for your question on Health Care Magic. I can understand your concern. Since your extensive cardiac work up is normal, no need to worry for heart related causes. By your history and description, in my opinion, you are mostly having stress related symptoms. Stress can cause chest tightness, pressure and chest pain due to GERD (gastroesophageal reflux disease). Stress is also a cause for tension headache and vertigo. So better to consult psychiatrist and get done counseling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic drugs too. So avoid stress and tension. Be relax and calm. Don t worry, you will be alright. Wish you good health. Thanks.
