Does a heart attack start in the arm?

??? The pain of heart attack may only be felt in the arm and not in the chest if that's what you mean and the answer is yes. Hehehe, i was gonna say heart attack always starts in the heart as a joke but i did not want you to misunderstand my joke, now i can say it since i answered your question.
Heart attack. The pathology starts inside a heart artery. The symptom felt can be chest, arm, neck discomfort, shortness of breath, lightheaded ness or other symptoms.
