Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that heart pains have some characteristics.They usaly are retro-sternal pains like squizzing , tightness or heaviness. They may irradiate to both arms, neck and jaw. They last from 5 to 20 minutes. We suspect
heart disease if we are in front of a patient whith risc factors like age over 45,
hypertension,
diabetes, smoker and whith hereditary history of cardiac disease.
Chest pains might have different causes like muscular, sceletic, neurotic or gastrointestinal.
So, if you explain pain that relives after consumption of milk this makes us thing of a gastric problem.
So, if I was the treating doctor I will recommend some examination like an electrocardiogram, a cardiac echo , a strees test, a thorax rx and a gastrohepatologyst consulting.
After all this we can better judge what we are dealling whith or if its just
stress or neurotic pain that soon will disappear.
Hope I was helpfull..
Best regards, Dr.Ervina.
