Hello! Welcome and thank you for asking on HCM! I passed carefully through your question and understand your concern. It is important making a careful differential diagnosis of your symptoms: - a backbone disorder, leading to irradiating pain in the arms, related to a slipped disc could mimic this symptomatology. -an ischemic heart disease, could explain the pain while exercising, but not the irradiating pain in both arms. -gastro esophageal reflux, could be related to heartburn during physical activity. I recommend consulting with your attending physician for a careful physical examination and some tests: -resting ECG -chest X ray study -cervico-thoracic column X ray study -lab blood tests (complete blood count, PCR, sedimentation rate, amylaze plasma levels, kidney and liver function tests). A cardiac stress test may be needed to exclude a cardiac ischemic disease if suspicions are raised. A fibrogastroscopy may be needed if all the above tests result normal, to exclude possible reflux. Hope to have been helpful! Greetings! Dr. Iliri
