Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms don t seem to be related to any cardiac disorders. The pain which is modulated by the body movements is characteristic of musculo skeletal disorders. So don t worry about it! It seems to be a benign disorder. 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 (inflammation tests) - kidney and liver function tests - blood electrolytes A cervico-thoracic column x ray study may be necessary to exclude possible column disorders, which could be associated to your symptoms. Meanwhile, I would recommend taking some painkillers like acetaminophen or ibuprofen for the pain, for some days. Hope to have been helpful! Best wishes, Dr. Iliri
