Chest Pain: When It's an Emergency and When It Can Wait
Not every chest pain is a heart attack — but some are. Learn the warning signs that mean call emergency services now, and the causes that are far more common.
Published · Updated
If you are having chest pain right now along with shortness of breath, sweating, nausea, or pain spreading to your arm, jaw, or back — stop reading and call your local emergency number. Do not drive yourself.
Chest pain is one of the most common reasons people seek urgent medical help, and one of the hardest symptoms to interpret on your own. The same sensation can come from the heart, the lungs, the muscles of the chest wall, the oesophagus, or from anxiety — and the pain itself does not reliably tell you which.
What follows is not a way to diagnose yourself. It is a way to decide how urgently you need to be seen, which is a different and much safer question.
Call emergency services immediately if
These features raise the probability that chest pain is cardiac in origin, and every one of them is a reason to be assessed within minutes rather than hours:
- Pressure, tightness, squeezing or heaviness in the centre of the chest lasting more than a few minutes, or coming and going
- Pain radiating to the jaw, neck, shoulder, one or both arms, or between the shoulder blades
- Shortness of breath, with or without pain
- Cold sweat, nausea, vomiting, or a sense of impending doom
- Light-headedness or fainting
- Sudden, tearing pain in the chest or upper back
- Chest pain in anyone with known coronary artery disease, diabetes, or a previous heart attack
Two groups often present without the classic crushing chest pain: women and people with diabetes. Fatigue, breathlessness, nausea, or discomfort in the upper back or jaw may be the only sign. Under-reacting is the common error here, not over-reacting.
Causes that are far more common than a heart attack
Most chest pain is not cardiac. Frequent culprits include:
Musculoskeletal pain. Strained chest wall muscles or inflamed cartilage where the ribs meet the breastbone. The giveaway is that it hurts more when you press on the spot, twist, or take a deep breath — and it can persist for days.
Acid reflux. A burning sensation behind the breastbone, often worse lying down or after a large meal, sometimes with a sour taste. Reflux and cardiac pain overlap enough that reflux is a diagnosis to be given, not one to assume.
Anxiety and panic. Real, physical chest tightness with a racing heart, tingling in the fingers, and rapid breathing. A panic attack is a genuine medical event, not something to be embarrassed about — but a first episode deserves assessment rather than self-labelling.
Respiratory infection. Chest soreness from persistent coughing, usually alongside fever or congestion.
What raises your baseline risk
Risk factors do not cause today's pain, but they change how cautious you should be about it: age over 45 for men and 55 for women, high blood pressure, high cholesterol, diabetes, smoking, obesity, a sedentary routine, and a family history of early heart disease. If several apply to you, treat new chest pain as a reason to be seen rather than a reason to wait it out.
When to book an appointment rather than call an ambulance
If your pain is mild, clearly reproducible by pressing or moving, has been stable for weeks, and comes with none of the emergency features above, a scheduled appointment is reasonable. Bring:
- When it started and what you were doing
- What makes it better or worse
- How long each episode lasts
- Any medication you take, including over-the-counter drugs and supplements
- Your family history of heart disease
That list is worth writing down before the visit. Under time pressure, patients routinely forget the detail that turns out to matter.
The rule worth remembering
Clinicians assess chest pain by ruling out the dangerous causes first and arriving at the benign ones by elimination — because the cost of missing a heart attack is measured in heart muscle, and the cost of an unnecessary assessment is a few hours. Chest pain that is new, severe, or different from anything you have felt before deserves urgent assessment, full stop.
Frequently asked questions
Can anxiety cause real chest pain?
Yes. Panic attacks produce genuine physical chest tightness, a racing heart, and breathlessness — the symptoms are real, not imagined. But because the presentation overlaps with cardiac pain, a first episode should be medically assessed rather than self-diagnosed as anxiety.
How can I tell heartburn from a heart attack?
You often cannot, reliably, and that is precisely the problem. Heartburn tends to burn, worsen when lying down, and follow meals; cardiac pain tends to feel like pressure and may spread to the arm or jaw. The overlap is wide enough that reflux should be a diagnosis you are given after assessment, not one you assume.
Does chest pain that lasts only a few seconds mean it is harmless?
Very brief, sharp, pinpoint pains are less often cardiac than sustained pressure lasting minutes. That is a tendency, not a guarantee — brief pain in someone with known heart disease or several risk factors still warrants assessment.
Should I take aspirin if I think I am having a heart attack?
Emergency dispatchers commonly advise chewing aspirin during a suspected heart attack, but it is not right for everyone — bleeding disorders and allergies matter. Call emergency services first and follow the instructions the dispatcher gives you.
