What does pulmonary embolism chest pain feel like? 

A pulmonary embolism occurs when a blood clot blocks an artery in the lung, which can lead to various physical sensations, most notably chest pain. Understanding the specific nature of this pain is essential for distinguishing it from other conditions and ensuring that medical help is sought when necessary. This article provides a detailed overview of the characteristics of chest pain associated with a pulmonary embolism and how it typically presents in patients. 

What We’ll Discuss in This Article 

• The primary sensations and characteristics of pulmonary embolism chest pain. 

• How breathing and movement affect the intensity of the discomfort. 

• The location of the pain and where it may spread. 

• Differences between pulmonary embolism pain and heart attack pain. 

• Other symptoms that often occur alongside chest discomfort. 

• When to seek immediate emergency medical care in the UK. 

Pulmonary embolism chest pain is typically sharp and worsens with breathing 

The chest pain associated with a pulmonary embolism is most often described as a sharp, stabbing sensation that occurs suddenly. This type of discomfort is known as pleuritic chest pain, meaning it is directly related to the inflammation of the lining of the lungs caused by the blockage. It is distinct from the dull or heavy sensations often linked to other cardiovascular issues. 

The NHS states that the pain is usually sharp and may feel worse when you breathe in, cough, or sneeze. Because the pain is mechanical in nature, taking a deep breath can feel particularly difficult or restricted. This sensation does not typically improve with rest or by changing your body position, as the underlying cause is a physical obstruction within the pulmonary circulation. 

The pain is often localised but can spread to other areas 

While the sharp sensation is often felt in a specific area of the chest, it can sometimes be felt in the upper back or under the ribs. The exact location usually corresponds to where the blood clot has lodged within the lung tissue. In some instances, the pain may feel as though it is coming from the side of the chest rather than the centre. 

NICE clinical guidelines indicate that pleuritic chest pain is a key diagnostic feature used by healthcare professionals to assess the likelihood of a pulmonary embolism. While the pain is primarily in the chest, the general sense of discomfort can occasionally radiate toward the shoulder or neck, though this is less common than the focused, stabbing sensation in the ribcage area. 

Distinguishing pulmonary embolism from heart attack pain 

It is important for patients to recognise the differences in how chest pain presents, as a pulmonary embolism and a heart attack require different emergency responses. While both are serious, the physical sensations they produce are often quite distinct. 

Feature	Pulmonary Embolism Pain	Heart Attack Pain
Sensation	Sharp, stabbing, or piercing.	Heavy, crushing, or squeezing.
Breathing	Gets significantly worse when breathing in.	Usually unaffected by the mechanics of breathing.
Location	Often on one side or focused over the lungs.	Often central, may spread to arms or jaw.
Onset	Usually very sudden.	Can be sudden or build up over time.

Associated symptoms that accompany the chest pain 

Chest pain is rarely the only symptom present during a pulmonary embolism. Most individuals will also experience a sudden onset of shortness of breath, which may occur even while sitting still or resting. This combination of sharp pain and difficulty catching one’s breath is a strong clinical indicator of a lung clot. 

Other signs can include a rapid heart rate, feeling lightheaded, or a persistent cough. In some cases, the cough may produce small amounts of blood. Because many pulmonary embolisms originate from a blood clot in the leg, you may also notice swelling, redness, or pain in one of your calves. 

The impact of physical exertion on the sensation 

Any activity that increases the rate or depth of breathing will generally make pulmonary embolism chest pain feel more intense. Walking, climbing stairs, or even talking for extended periods can cause the sharp sensation to flare up because the heart and lungs are working harder. This is different from stable angina, where pain usually subsides relatively quickly once the physical activity stops. 

In a pulmonary embolism, the blockage remains in place regardless of whether the person is active or resting. However, the increased oxygen demand during movement makes the symptoms much more noticeable and distressing. This persistent nature of the pain is why medical professionals advise an immediate assessment if these sensations occur. 

Conclusion 

Chest pain in pulmonary embolism is characteristically sharp, stabbing, and becomes more intense when taking a deep breath or coughing. It is often accompanied by sudden breathlessness and a rapid heart rate, reflecting the strain on the respiratory and circulatory systems. Recognising these specific traits is vital for identifying this serious condition promptly. 

If you experience severe, sudden, or worsening symptoms, call 999 immediately.
