Anxiety Chest Pain — Why It Feels Like a Heart Attack (And Why It Isn't)

Chest pain is the anxiety symptom most likely to send people to A&E. The sensation can range from a dull ache to a sharp stabbing pain to a heavy pressure in the centre or left side of the chest — and it mimics cardiac chest pain so convincingly that even experienced clinicians initially take it seriously. The fear that chest pain generates creates more anxiety, which intensifies the chest pain, which creates more fear.

What Causes Anxiety Chest Pain

Anxiety chest pain is caused by several distinct mechanisms, all produced by the fight-or-flight response:

• Intercostal muscle tension — the muscles between the ribs tense under anxiety, causing aching or sharp pain
• Hyperventilation — rapid, shallow breathing changes blood CO₂ levels, causing chest tightness and pain
• Oesophageal spasm — anxiety can trigger spasms in the oesophagus that feel exactly like cardiac chest pain
• Costochondritis — inflammation of the cartilage between ribs and sternum, worsened by anxiety tension
• Pericardial tension — anxiety can cause transient inflammation or tension around the heart
• Heightened pain sensitivity — the anxious nervous system is hypervigilant to all physical sensations

How to Distinguish Anxiety Chest Pain from Cardiac Chest Pain

Always seek medical assessment for new or severe chest pain. Once cardiac causes have been excluded, the following characteristics are typical of anxiety chest pain: it changes in intensity with breathing or position; it is often accompanied by other anxiety symptoms (palpitations, dizziness, tingling); it tends to worsen with anxiety and improve when anxiety reduces; it is not brought on by physical exertion in the way cardiac pain is.

Eliminating Anxiety Chest Pain

Anxiety chest pain resolves completely when anxiety disorder resolves. The Linden Method reconditions the sensitised alarm centre, eliminating the anxiety response that generates the physical symptoms — including chest pain. Many participants report that chest pain, along with all other anxiety symptoms, clears within weeks of beginning the program.
