Hello! Welcome and thank your for asking on HCM! I read your question and understand your concern. Your symptoms may be related to a musculo-skeletal pain or an esophageal spasm. The fresh drink after physical exercise could trigger the above disorders. Did you have any other symptoms like chest pain, difficulty breathing, dizziness, etc. These symptoms could raise the suspicion of a cardiac cause. It is not typical of any cardiac disorder shock pain that lasts for seconds, without leaving any symptoms after. I would like to know your age and your past medical history. If these symptoms repeat, I recommend consulting with the GP for a careful physical examination, a resting ECG, a chest x ray and some lab tests (a complete blood count, inflammation tests, fasting glucose, kidney and liver function tests, blood electrolytes), to exclude other possible causes related to this clinical scenario. Hope to have been helpful! Best wishes, Dr. Iliri
