Quick answer. Call 112 or 108 now if chest pain or pressure lasts more than a few minutes, spreads to the arm, jaw, neck or back, or comes with sweating, sickness or breathlessness. Most chest pain is not serious, but gas and a heart attack can feel alike, so do not wait to find out at home.

Call 112 or 108 now if

These signs need an ambulance, even if the pain is not severe and even if it might be gas.

This page is general information. It cannot tell you what is causing your pain. Only an examination and tests can do that.

What to do while the ambulance comes

  • Do not drive yourself to hospital. Ask someone to stay with you.
  • Sit and rest, on the floor with knees bent and back supported, or on a chair.
  • Tell the call handler about any medicines and allergies, and ask whether to take aspirin. The NHS advises aspirin while waiting if it is at hand, unless the person is allergic to it.
  • If a doctor has already prescribed angina spray for you, use it as you were told.
  • If the person stops responding and stops breathing, start CPR and tell the call handler.
  • Take a list of current medicines and any old ECG or blood reports if they are close by. Do not spend time looking for them.

Speed matters because the early hours of a heart attack carry the greatest risk of sudden death. In India, the ICMR treatment workflow aims for an ECG ideally within 10 minutes of first medical contact, so that treatment can start quickly.

Is it gas or is it my heart?

This is the question most people ask, and the honest answer is that you cannot reliably tell at home. The NHS lists a burning chest and feeling full or bloated among heart attack symptoms, which is exactly how many of us describe gas or acidity. Its chest pain page also warns against diagnosing yourself.

Some people have very little pain at all. Older adults, people with diabetes and women may have little or no chest pain, and may notice breathlessness, tiredness or weakness instead. WHO notes that women more often report breathlessness, nausea, vomiting and back or jaw pain.

If you are unsure and the pain has not gone away within a few minutes, treat it as an emergency. Being sent home from casualty with a diagnosis of acidity is a good outcome.

Common causes of chest pain

Most chest pain is not caused by anything serious. The table below shows patterns the NHS and MedlinePlus describe. Use it to prepare for your talk with a doctor, and not to rule anything out. These patterns can overlap.

What people often noticePossible causeUsually seen by
Squeezing or pressure brought on by exercise, stress, cold or a large meal, easing within about 10 minutes of restAnginaGeneral physician, then cardiologist
Pain after eating, with sour burps and a full, bloated feelingHeartburn or indigestionGeneral physician, then gastroenterologist if it lasts
Pain after a chest injury or exercise, worse on breathing in and easing at restChest strain or sprainGeneral physician
Pain worse on breathing in, with fever and yellow or green phlegmChest infection, pneumonia or pleurisyGeneral physician the same day, then pulmonologist if needed
Sudden stabbing pain worse with deep breaths or lying downPericarditis, a heart causeEmergency department or cardiologist
Tingling skin, then a rash that turns to blistersShinglesGeneral physician or dermatologist
Sharp pain triggered by worry, with a fast heartbeat, sweating and dizzinessAnxiety or a panic attackGeneral physician first, then psychiatrist or psychologist

MedlinePlus also lists gallstones, stomach ulcers or gastritis, spasm of the food pipe, inflamed rib joints, a blood clot in the lung and a collapsed lung among possible causes. Some of these are minor and some are emergencies, which is another reason to get checked.

Who is at higher risk of heart causes

The NHS lists older age, smoking, obesity, high blood pressure, diabetes, high cholesterol, and a close relative who had a heart attack or angina before 60. Tell the doctor about any of these. Being young or fit does not mean you should ignore the emergency signs above.

Who to see if it is not an emergency

If the pain comes and goes, or went away quickly and you are still worried, see a doctor soon. A general physician usually checks this first and can do an ECG. If the pain comes on with effort and settles with rest, they will usually refer you to a cardiologist. Go to emergency if that pain lasts or starts coming on at rest.

MedlinePlus also advises seeing a doctor for fever with a cough that brings up yellow-green phlegm, trouble swallowing, or chest pain lasting more than 3 to 5 days.

Other specialists come in depending on what the first tests show: a gastroenterologist for lasting acidity, a pulmonologist for lung causes, and a psychiatrist for panic attacks once the heart has been checked.

What the doctor will do

The doctor will start with questions. MedlinePlus lists where the pain is, whether it spreads, how it feels, when it started, how long it lasts, and what makes it better or worse, such as breathing, eating, exercise, rest or antacids. Before you go, try to note:

  • When the pain started and what you were doing.
  • Whether it has happened before, and whether it is coming on more often.
  • Any breathlessness, sweating, sickness, fever or cough.
  • Your medicines, and any diabetes, blood pressure, cholesterol or smoking history.
  • Whether anyone in your family had heart disease at a young age.

Tests depend on the likely cause and your other health problems. For a suspected heart attack, doctors start with an ECG and blood tests. If those point to a heart attack, an echocardiogram checks for damage and a coronary angiogram shows where blood flow is blocked. The blockage may be treated during the same procedure.

Blood tests for heart damage are often repeated over time, so you may be asked to stay for a few hours even if the first results look normal. For angina, a doctor may also arrange blood tests, an ECG, a blood oxygen check and scans.

Common questions

Does heart pain always come on the left side?

No. MedlinePlus describes heart attack pain as tightness, pressure or heaviness that can spread to the arms, shoulder, neck, jaw, back or belly, and the NHS says the pain can spread to the left or right arm. Do not rely on which side it is on.

The pain has gone. Do I still need to be seen?

Yes. The NHS advises getting medical advice for chest pain that comes and goes, or that goes away quickly to make sure it is nothing serious. Angina, for example, usually passes within about 10 minutes, and it still needs a doctor. If the pain returns and does not settle, call 112 or 108.

Should I take an antacid first and see if it helps?

Do not let an antacid delay help. A heart attack can feel like indigestion. If any of the emergency signs at the top of this page are present, call first.

Could stress or panic be causing this?

It can. Anxiety and panic attacks can cause sharp chest pain with a fast heartbeat and sweating. The heart should still be checked first if the pain is new, because the symptoms overlap with heart causes.

My child complains of chest pain. Is it the heart?

MedlinePlus says most chest pain in children is not caused by the heart. A paediatrician can check. Call 112 or 108 if a child is struggling to breathe, unusually drowsy or floppy.
