What part of your left arm hurts when having a heart attack

Call 999 immediately if you think someone might be having a heart attack. The faster you act, the better their chances.

Symptoms of a heart attack

Symptoms of a heart attack can include:

  • chest pain – a feeling of pressure, heaviness, tightness or squeezing across your chest
  • pain in other parts of the body – it can feel as if the pain is spreading from your chest to your arms (usually the left arm, but it can affect both arms), jaw, neck, back and tummy
  • feeling lightheaded or dizzy
  • sweating
  • shortness of breath
  • feeling sick (nausea) or being sick (vomiting)
  • an overwhelming feeling of anxiety (similar to a panic attack)
  • coughing or wheezing

The chest pain is often severe, but some people may only experience minor pain, similar to indigestion.

While the most common symptom in both men and women is chest pain, women are more likely to have other symptoms such as shortness of breath, feeling or being sick and back or jaw pain.

Waiting for an ambulance

If you have had a heart attack, it's important that you rest while you wait for an ambulance, to avoid unnecessary strain on your heart.

If aspirin is available and you are not allergic to it, slowly chew and then swallow an adult-size tablet (300mg) while you wait for the ambulance.

Aspirin helps to thin your blood and improve blood flow to your heart.

Cardiac arrest 

In some cases, a complication called ventricular arrhythmia can cause the heart to stop beating. This is known as sudden cardiac arrest.

Signs and symptoms that suggest a person has gone into cardiac arrest include:

  • they appear not to be breathing
  • they're not moving
  • they don't respond to any stimulation, such as being touched or spoken to

If you think somebody has gone into cardiac arrest and you do not have access to an automated external defibrillator (AED), you should perform chest compressions, as this can help restart the heart.

Chest compression

To do chest compressions on an adult:

  1. Place the heel of your hand on the breastbone at the centre of the person's chest. Place your other hand on top of your first hand and interlock your fingers.
  2. Using your body weight (not just your arms), press straight down by 5 to 6cm on their chest.
  3. Repeat this until an ambulance arrives.

Aim to do 100 to 120 compressions a minute. Watch the video on "hands-only" CPR from the British Heart Foundation.

Automated external defibrillator (AED)

If you have access to an AED, you should use it. An AED is a safe, portable electrical device that most large organisations keep as part of first aid equipment.

It helps to establish a regular heartbeat during a cardiac arrest by monitoring the person's heartbeat and giving them an electric shock if necessary.

Angina and heart attacks

Angina is a syndrome (a collection of symptoms caused by an underlying health condition) caused by the supply of oxygen-rich blood to the heart becoming restricted.

People with angina can experience similar symptoms to a heart attack, but they usually happen during exercise and pass within a few minutes.

However, occasionally, people with angina can have a heart attack. It's important to recognise the difference between the symptoms of angina and those of a heart attack. The best way to do this is to remember that the symptoms of angina can be controlled with medicine, but symptoms of a heart attack cannot.

If you have angina, you may have been prescribed medicine (glyceryl trinitrate) that improves your symptoms within 5 minutes. If the first dose does not work, a second dose can be taken after 5 minutes, and a third dose after a further 5 minutes.

If the pain persists, despite taking 3 doses of glyceryl trinitrate over 15 minutes, call 999 and ask for an ambulance.

What part of your left arm hurts when having a heart attack
Cath Haywood recalls the day in 2006 when she felt a bit “under the weather”. She told her family that her arm ached. At first, she attributed the arm pain to over-enthusiastic ball throwing – she had been tossing lobs to her springer spaniel earlier that day. But on the following evening, the 49-year old former Welsh police officer again experienced what she describes as “a dreadful ache in my right arm”. She remembers thinking:

“I’ve really got to lay off throwing that ball!”

As the arm pain got worse, Cath brushed aside pleas from her husband and two sons to call an ambulance, and she went to bed. After all, as she told herself, she was fit, relatively young, had just lost 28 pounds, did not smoke, and drank only occasionally. So why bother the ambulance crew? 

Finally, however, she relented, and was shocked to learn at the hospital that she had indeed suffered a heart attack.

She was also shocked to find out that in at least 10% of women’s heart attacks,  there is no form of chest pain at all.(1) Nothing. Zero. Zilch. Nada.

Although in many heart attacks, pain can begin in the chest and spread to other areas, even when there’s no chest pain as an initial symptom, heart attack signs may include pain or discomfort in the left, right or both arms or in the shoulders, elbows, back, neck, throat, lower jaw or stomach. Or as Mayo Clinic cardiologists call it: anything “from neck to navel”.

Men having a heart attack often feel pain in the left arm. In women, the pain is more likely to be felt in either arm. The pain might also come and go. Fun fact: pain in your right arm or shoulder appears to double the likelihood of a heart attack diagnosis compared to symptoms in the left arm.(2)

In a previous post called “How Does It Really Feel to Have a Heart Attack? Women Survivors Tell Their Stories”, a number of women interviewed also described unusual elbow pain as an early heart attack symptom.

Why would a heart attack cause pain or discomfort in our arm?

Here’s the technical gobbledygook reason, according to an Indiana cardiac surgeon who answered a patient’s question on HealthTap:

“The pericardium is innervated by C3,4,5 (Phrenic nerve). There may be some neuronal connections to the intercostobrachial nerves.”

(And doctors sometimes wonder why their patients don’t seem to understand them . . .)

Allow me to translate that HealthTap Geek-Speak for you: basically, it’s because of referred pain to the arm.

For example, your heart attack may cause a sensation of pain to travel from your heart to your spinal cord, where many nerves merge onto the same nerve pathway. Your arm may be perfectly fine, but your brain thinks that part of the heart’s pain is the arm (or the jaw or the shoulder or the elbow or the neck or the upper back) calling out for help. That’s what referred pain is.

When  your heart muscle cells begin to run out of oxygen during a heart attack because of a blocked artery preventing oxygenated blood from feeding that muscle, they begin to send off signals of pain through the nervous system. Your brain may confuse those nerve signals with signals coming from the arm (or the jaw, shoulder, elbow, neck or upper back) because of the nerve proximity.

So there are times that we can feel both chest pain and arm pain when our heart muscle is not getting enough oxygen, but there are other times that discomfort in either arm (or the jaw, shoulder, elbow, neck or upper back) may be the only symptom of a heart attack.

In fact, arm pain may be one of the first indications that a heart attack is about to occur. Arm pain has also been reported as the cause of significant sleep disturbances even days before a heart attack.

You might not even describe this symptom as “pain”.  Instead, you may feel it as electrical, tingling, pins-and-needles, dull ache, weakness, heaviness, fullness, or a crushing feeling.

These symptoms may come and go, and can also fluctuate in severity. They can hit both before and during a heart attack. And remember that heart attack symptoms don’t necessarily include any arm discomfort.

What else could it be?

Arm pain on its own, of course, can have nothing to do with heart issues. Intermittent arm pain may be due to something as simple as repetitive strain injuries experienced during typing, video gaming or text messaging, especially if done while in an awkward position or while leaning forward to see the screen.

Arm pain can also be caused by a number of other factors. Try keeping a log of symptoms, the severity, time and date they occurred, what you were doing/eating/feeling in the hours leading up to that symptom.  Ask your doctor about all possible causes of arm pain, especially if pain becomes severe.
