Yes, chest pain is a recognized symptom of COVID-19. It can occur during the acute infection or persist for weeks afterward, and it shows up in roughly 23% of people who develop long COVID. The pain has several possible causes, ranging from sore chest muscles due to coughing to more serious complications like heart inflammation or blood clots. Understanding what’s behind the pain helps you figure out whether it’s something that will resolve on its own or something that needs immediate attention.
Why COVID Causes Chest Pain
There isn’t a single explanation for COVID-related chest pain. The virus affects multiple systems in the body, and each one can produce a different type of chest discomfort. The most common causes fall into four categories: muscular soreness, lung inflammation, heart involvement, and blood clots.
The simplest and most frequent cause is muscular. COVID-19 causes body aches, and the muscles of the chest wall and the muscles involved in breathing are no exception. Prolonged or severe coughing can also strain these muscles, producing a soreness that worsens when you move, twist, or take a deep breath. Some people develop a condition called Tietze syndrome after COVID, where the cartilage connecting the ribs to the breastbone becomes inflamed and swollen. This creates a localized, tender pain right at the chest wall that can feel alarming but isn’t coming from the heart or lungs.
Lung-Related Chest Pain
COVID-19 can inflame the lining of the lungs, a condition called pleurisy. This produces a sharp, stabbing pain that gets worse when you breathe in deeply or cough. In some cases, pleurisy has been the very first symptom of COVID, appearing before fever or cough. COVID pneumonia, where the infection causes fluid and inflammation in the lung tissue itself, can also create a feeling of tightness or pressure in the chest, sometimes accompanied by shortness of breath.
Heart Inflammation
One of the more concerning causes of chest pain during or after COVID is myocarditis, inflammation of the heart muscle. The virus doesn’t necessarily infect the heart directly in every case. Instead, the intense immune response triggered by the lung infection can spill over, with inflammatory signals and tiny virus-carrying particles traveling through the bloodstream to the heart. Once there, they can damage heart muscle cells and trigger an autoimmune response where the body’s own immune system attacks cardiac tissue.
When the virus binds to receptors on blood vessel walls, it disrupts their normal function. This can raise blood pressure and promote further inflammation, which partly explains why people with existing high blood pressure, diabetes, or heart disease face higher risks from COVID. Myocarditis from COVID presents with chest pain or pressure, palpitations, shortness of breath, and fatigue. In one Israeli study of vaccine-associated myocarditis cases (which share a similar presentation), 81% of patients reported chest pain as their primary symptom. Pericarditis, inflammation of the thin sac surrounding the heart, can also occur and produces similar symptoms.
Blood Clots in the Lungs
COVID-19 creates a state where the blood clots more easily than normal. The infection damages the lining of blood vessels and ramps up clotting factors while suppressing the body’s ability to break clots down. Combined with the low oxygen levels that severe pneumonia causes, this environment encourages clot formation. In one hospital study, 22% of COVID pneumonia patients were found to have pulmonary embolism, a blood clot in the lungs, on CT scans.
A pulmonary embolism typically causes sudden, sharp chest pain that worsens with breathing, along with shortness of breath and sometimes a rapid heartbeat. Patients who developed these clots were more likely to need intensive care and had a fatality rate of 10% in that study. This is the most dangerous cause of COVID-related chest pain and the main reason persistent or worsening chest symptoms shouldn’t be ignored.
How to Tell What’s Causing Your Chest Pain
The quality, location, and timing of the pain offer useful clues. Muscular chest pain tends to be sore or achy, worsens with movement or pressing on the area, and often follows days of heavy coughing. Pleuritic pain from lung inflammation is sharp and tied closely to breathing. Heart-related pain usually presents as pressure or a squeezing sensation and may come with palpitations or feeling faint.
Heart attack pain, which COVID can also trigger in some cases, often radiates to the arms, jaw, or back. Anxiety-related chest pain, which is common during any illness, typically peaks within about 10 minutes and then fades, tends to happen at rest rather than during activity, and doesn’t spread to the arms or back. Paying attention to accompanying symptoms helps too. If the chest pain comes with a new fever, worsening shortness of breath, or a racing heart, the cause is more likely to be cardiac or pulmonary than muscular.
The CDC lists “persistent pain or pressure in the chest” as an emergency warning sign of COVID-19. If your chest pain is constant, getting worse, or accompanied by difficulty breathing, confusion, or bluish lips, that warrants emergency care.
Chest Pain After Recovery
For many people, chest pain doesn’t end when the acute infection clears. A large meta-analysis found that 23% of people with long COVID reported chest pain, with symptoms lasting a median of two months. Other common lingering symptoms included fatigue (34%, lasting about 5.5 months), anxiety and depression (31%), and shortness of breath (24%, lasting over 6 months).
Post-COVID chest pain can stem from lingering inflammation in the heart or lungs, ongoing chest wall irritation like Tietze syndrome, or a combination of deconditioning and heightened nervous system sensitivity. For most people, the pain gradually resolves over weeks to a few months. If it persists beyond that or interferes with daily activities, a medical evaluation can help identify whether there’s an underlying issue like subclinical myocarditis or residual lung inflammation that needs treatment.
