Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I passed carefully through your question and would explain that it is important performing a comprehensive differential diagnosis between different possible causes that may lead to this clinical situation: coronary artery disease, a bulging disc in the cervical vertebral column, acid reflux or just anxiety. For this reason, I would recommend consulting with your attending physician and performing some tests: - A resting ECG and a cardiac ultrasound - An exercise cardiac stress test - A cervical spine X ray study - Thyroid hormone levels for thyroid gland dysfunction - Blood electrolytes for any possible imbalances. A fibrogastroscopy may be needed, especially if all the above tests result normal. Hope I have answered your query. Let me know if I can assist you further.
