Hello! Welcome and thank you for asking on HCM! I read your question carefully and understand your concern. It is important to perform a differential diagnosis between different causes of chest pain related to the heart, chest, muscles, soft tissues, bones, gastro esophageal junction etc. Is this pain triggered by respiration or body movements? This would indicate a musculo skeletal pain. What are your heart rhythm values? How long does this feeling go on? I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest X ray study and some blood lab tests (complete blood count, PCR, sedimentation rate, kidney and liver function tests, blood electrolytes, etc.). A fibrogastroscopy may be needed to exclude possible gastroesophageal reflux, is suspicions are raised. If all the above mentioned tests result normal, you should take into consideration anxiety as a possible cause of these troubles. Hope to have been helpful! Greetings! Dr. Iliri
