Hello Jitendra! Welcome on HCM! I carefully read your question and would explain that it is important performing a comprehensive differential diagnosis between different causes that may lead to this clinical scenario: - coronary artery disease (considering that you suffer from arterial hypertension, which is a known cardio-vascular risk factor) - a lung disorder - a musculo skeletal pain - a backbone disorder Is the chest pain triggered by deep breathing or a certain body position? This would be indicative of musculo-skeletal pain. Coming to this point, I would recommend consulting with your doctor for a careful physical exam and some tests: - a resting ECG and cardiac ultrasound - a cardiac stress test (TMT) - a lung X ray study - a cervico-thoracic spine X ray study - some blood lab tests (complete blood count, PCR, ESR). Hope to have been helpful! Kind regards, Dr. Iliri
