Hello! Thank you for asking on HCM! Regarding your concern, I would like to explain that your symptoms don t seem to be cardiac related. Is this pain modulated by respiration or the body movements? A comprehensive differential diagnosis between different disorders (like costochondritis, pleurits, pericarditis, a musculoskeletal pain, pneumonia,etc) which could mimic this clinical scenario should be done. I would recommend consulting with your GP for a careful physical examination, a resting ECG and a cardiac ultrasound, a chest x ray study and some lab blood tests (complete blood count, PCR, sedimentation rate, kidney and liver function tests, blood electrolytes, etc.). If all the above tests result normal, the main cause of this symptomatology would be a muskuloskeletal pain. In such case, painkillers (like ibuprofen, acetaminophen, etc) for a short period of time would be helpful. Hope to have been of help! Feel free to ask any other questions, whenever you need! Best wishes, Dr. Iliri
