Hello! Thank you for asking on HCM! I understand your concern, and would explain that your symptoms don t seem to be cardiac related. This symptomatology is probably related to acute gastritis , esophagitis or gastro esophageal reflux. Do you have any other symptoms like burping or nausea? I recommend using PPIs (omeprasole, lansoprazole, etc) or an antiacid. If your symptoms are relieved by one of this drugs, it would be very indicative for a gastro esophageal disorder. If the problem persists, your should consult with a gastroenterologist and perform a GI endoscopy to rule in/out the above mentioned disorders. Hope to have been helpful! Best wishes, Dr. Iliri
