eft Shoulder Pain or Heart Attack_ How to Tell the Difference Heart attacks are often associated with shoulder pain on the left side. Although shoulder pain is quite a common symptom of some other conditions such as cold, having pain specifically on the left side of the shoulder should not be ignored. Thus, identifying cardiac-related shoulder pain can help in potentially life-saving early interventions.

How to tell if shoulder pain is heart-related

The left shoulder is closest to where the heart is seated. Any pain on the left side of the shoulder is thus treated as cardiac-related. It can be a potential warning sign that should not be ignored by a person experiencing the pain.

When to worry about shoulder pain

For identifying if you are having a heart attack while experiencing left shoulder pain, it is important to know how heart-related shoulder pain feels. Such pain that begins on the left side of the shoulder has some typical attributes. Read on to find out more…

Radiating pain: A typical shoulder pain that is associated with heart attack is known for its radiating pain which originates from the chest into the left shoulder and sometimes, to the right shoulder as well. This radiating pain is felt as a heavy or squeezing sensation unlike the sharp pain that is felt if you suffer from any musculoskeletal issue.
Persistent pain: Heart-related shoulder pain does not ease with rest. Instead, it is exacerbated with physical activity or increased stress levels. This escalation in shoulder pain when accompanied by other heart attack symptoms such as chest pain, is a concerning symptom which should not be ignored.

While most heart-related shoulder pain starts at the left shoulder, it can often affect the right side of the shoulder as well.

Warning signs of heart attack in women and men

Apart from shoulder pain, heart attacks in men and women are accompanied by other symptoms as given below:

Chest pain: It occurs as a crushing or burning sensation and is usually felt behind the breastbone or the left side of the chest. This is perhaps the most widely recognized symptom of a heart attack.
Nausea and sweating: Nausea or vomiting, accompanied by profuse sweating, is indicative of an imminent heart attack.
Shortness of breath: Shortness of breath can be experienced as rapid, shallow breathing, or a feeling of breathlessness. When accompanied by shoulder pain, it can be a cause for grave concern.
Fatigue: Fatigue or unexplained tiredness is another tell-tale sign that you are experiencing a heart attack. This feeling of tiredness doesn’t go away despite lying down for a while or taking rest.

Does heart attack cause pain in arm and shoulder

Incidentally, when a heart attack occurs, it can cause pain in one or both the arms, in particular the left arm, which radiates towards the left shoulder. This is one of the more evident signs that you are having a heart attack if you experience such pain.

Conclusion

The ideal thing to do under such a scenario is to rest while you call the emergency helpline number for an ambulance. Care should be taken that the heart is not put under any unnecessary strain during this time. With timely help and medical intervention, you can avert a catastrophic heart attack from taking place.

Frequently Asked Questions

Can left shoulder pain be a sign of a heart attack?

Yes, left shoulder pain can indeed be a sign of a heart attack. Discomfort from the chest starts to radiate outwards, particularly towards the left shoulder and arm. This is known as referred pain and is more commonly seen in men than women.

What are the early symptoms of a heart attack?

Some of the early symptoms of a heart attack include chest pain, shortness of breath, nausea and sweating, and unexplained fatigue.

How is heart attack pain different from muscle pain?

Unlike musculoskeletal pain which subsides after taking adequate rest, pain due to heart attack does not get relieved even with changes in position or rest. Cardiac-related pain is radiating in nature and spreads from the chest to the arms and shoulder.

Should I go to the ER for unexplained shoulder pain?

You should go to the ER immediately if you experience unexplained shoulder pain that comes suddenly and is severe or if it is accompanied by chest discomfort, tightness, or pressure. These could be possible signs of a developing heart attack and require immediate medical attention.

Is shoulder pain alone enough to suspect heart issues?

No, shoulder pain alone cannot be taken as a confirmation of suspected heart issues. Shoulder pain can also arise as a result of musculoskeletal issues.

What tests help confirm if pain is heart-related?

There are few tests such as electrocardiograms (ECGs) and imaging tests such as echocardiograms, CT scan, and MRI scan which can help confirm if pain is heart-related.
