Thanks for the question. If there is a fear of an acute coronary event, going to the emergency room is important and could save your life. Better safe than sorry. If nothing is found, they can refer you to your primary care doctor. Urgent care is a nice medium between ER and regular doctor. But ruling out something serious is always the best course of action with heart health. https://www.healthline.com/health/heart-attack/urgent-care-for-heart-attack
If you have any reason to believe you have cardiovascular problems, your family doctor will make a referral to a specialist. The Internet will give you a list of possible symptoms, including “none”.
