Pleurodynia is a viral illness that causes sudden, sharp chest or abdominal pain, most often triggered by group B coxsackieviruses. The condition goes by several names, including Bornholm disease and the more dramatic “devil’s grip,” a nod to the vise-like spasms patients describe. Though the pain can be alarming enough to send someone to the emergency department, pleurodynia is almost always self-limiting and resolves without lasting damage. Its real significance lies in how convincingly it mimics far more dangerous conditions.
What Causes Pleurodynia
The chief culprits are group B coxsackieviruses, a family of enteroviruses that spread through the fecal-oral route and, to a lesser extent, respiratory droplets. Among those, Coxsackievirus B3 and Coxsackievirus A9 are the strains most frequently linked to epidemic outbreaks, and the illness they produce looks essentially identical regardless of which strain is responsible.1PubMed Central. Unusual cause of chest pain, Bornholm disease, a forgotten entity; case report and review of literature Other coxsackievirus A types (4, 6, and 10) and several echovirus types (1, 6, 8, 9, and 19) have also been documented as causes, though they appear less frequently in surveillance data.
Echovirus type 1, for example, was identified in a traveler returning from the tropics who developed classic Bornholm disease. Despite being one of the recognized pathogens behind the condition, that particular genotype had rarely surfaced in Western surveillance reports, suggesting that some of these viruses circulate more quietly than the headline strains.2PubMed. Pleurodynia caused by an echovirus 1 brought back from the tropics The variety of viruses capable of causing pleurodynia is part of the reason the illness can pop up in unexpected places and at unexpected times.
How the Virus Reaches Your Muscles
The most likely point of entry is the pharynx. Once the virus takes hold, it replicates in nearby lymphatic tissue and then enters the bloodstream, traveling to the striated muscles of the chest wall, diaphragm, and abdomen.3PubMed Central. Unusual cause of chest pain, Bornholm disease, a forgotten entity; case report and review of literature This is different from a respiratory infection that stays in the lungs or airways. Pleurodynia is fundamentally a muscle disease: the virus sets up camp in the intercostal muscles (the small muscles between your ribs) and sometimes in the diaphragm itself. The resulting inflammation, and in some cases actual muscle-cell death, is what produces the intense pain. Because the pleura, the thin membrane lining the chest cavity, lies just underneath those muscles, the inflammation irritates it too, giving the pain its characteristically sharp, breath-dependent quality.
What the Pain Feels Like
Pleurodynia typically arrives a few days after exposure to the virus. The hallmark is sudden, severe chest or upper abdominal pain that seems to come out of nowhere. It tends to be unilateral, affecting just one side, and it worsens with deep breathing, coughing, or any movement that shifts the chest wall. Some people describe it as knife-like spasms that last roughly fifteen to thirty minutes, followed by a period of dull ache or temporary relief before the next wave hits.
Fever is the most common accompanying symptom, reported in roughly 70% of cases. The characteristic “devil’s grip,” that distinctive thoracic stitch, shows up in about 40% of patients.4PubMed Central. Unusual cause of chest pain, Bornholm disease, a forgotten entity; case report and review of literature Other symptoms can include headache, sore throat, and general malaise, the kind of low-grade sick feeling that accompanies many viral infections. Pain sometimes radiates to the neck or arms, which is precisely the pattern that makes clinicians worry about cardiac problems.
The spasmodic nature of the pain is worth understanding. Unlike the constant, grinding ache of something like a muscle strain, pleurodynia pain tends to come in waves. A patient might feel nearly normal for an hour or two, then get hit with another round of spasms. This cycling pattern can last anywhere from a couple of days to a couple of weeks, though most people feel substantially better within a week.
When It Looks Different in Children
Pleurodynia in children does not always follow the adult script, and that discrepancy has been recognized for a long time. Early clinical reports noted that the disease in young children could present with features that departed significantly from the well-known adult picture, leading to initial misdiagnosis even during known outbreaks.5JAMA Pediatrics. Acute Epidemic Myalgia or Pleurodynia: Clinical Course and Diagnosis of the Disease in Children
Children are more likely to present with abdominal pain rather than chest pain, which steers clinical thinking toward gastrointestinal causes. Younger children may also have a harder time describing the episodic, spasmodic quality of the pain, so what an adult might report as “waves of stabbing chest pain” comes across as a fussy, inconsolable child with a stomachache. When a child shows up to a clinic during the summer months with fever and unexplained abdominal pain, pleurodynia belongs on the list, especially if there is a known enteroviral outbreak in the community.
Why It Gets Mistaken for an Emergency
The combination of sudden-onset chest pain, fever, and difficulty breathing is a clinical alarm bell that rings for a long list of serious conditions. The differential diagnosis for pleurodynia includes acute appendicitis, pancreatitis, gallbladder inflammation, pulmonary embolism, and acute coronary syndromes, among others. Some of those diagnoses are life-threatening if missed.6PubMed Central. Unusual cause of chest pain, Bornholm disease, a forgotten entity; case report and review of literature
This creates a double-edged problem. On one side, a patient with pleurodynia may undergo expensive and invasive testing, cardiac workups, CT scans, even exploratory surgery, before anyone lands on the relatively benign viral diagnosis. On the other side, dismissing chest pain as “just a virus” without adequate evaluation could miss a genuine emergency. Awareness of pleurodynia as a diagnostic possibility helps clinicians avoid both traps: they can include it early in their thinking when the clinical picture fits, order appropriately targeted testing, and potentially spare the patient unnecessary procedures.7JAMA. Clinical and Epidemiologic Aspects of Epidemic Pleurodynia
The irony is that pleurodynia has become something of a forgotten diagnosis. As large-scale epidemics have become less common in high-income countries, fewer clinicians have seen the condition firsthand. A disease that was once well recognized during summer outbreaks has faded from the front of the diagnostic mind, making misdiagnosis more, not less, likely than it was decades ago.
How It Spreads and Who Gets Hit
Enteroviruses spread readily in warm weather. Pleurodynia classically peaks in summer and early fall in temperate climates, when people are outdoors, in close contact, and sharing food, drink, and swimming water. The fecal-oral route is the primary means of transmission, though respiratory droplets play a supporting role. Children and young adults are disproportionately affected, partly because they are more likely to be in the kinds of communal settings, schools, sports teams, summer camps, where the virus circulates efficiently.
One well-documented outbreak among high school football players in the United States illustrates the mechanics perfectly. About 20% of the team fell ill, and the investigation traced the spread to shared water containers. Behaviors like eating ice cubes from a communal ice chest or drinking from the team cooler were strongly associated with illness. Coxsackievirus B1 was isolated from stool samples of half the tested players.8JAMA. Pleurodynia Among Football Players at a High School The episode led to recommendations against direct oral contact with shared drinking containers and a shift toward individual water bottles and ice packs, advice that has since become standard hygiene practice in team sports for a range of infectious diseases.
Outbreaks can also crop up in families, where one child brings the virus home and siblings or parents fall ill over the following week. In some historical epidemics, entire towns saw clusters of cases. The name “Bornholm disease” itself traces back to an outbreak on the Danish island of Bornholm in the 1930s, which put the condition on the map as a distinct clinical entity.
Potential Complications
Pleurodynia is overwhelmingly benign. The vast majority of patients recover completely without any lasting effects, and the illness follows a self-limited course.9JAMA. Clinical and Epidemiologic Aspects of Epidemic Pleurodynia That said, the coxsackieviruses that cause pleurodynia are not confined to muscle tissue. The same viruses are known to cause viral meningitis, pericarditis (inflammation of the sac around the heart), and myocarditis (inflammation of the heart muscle itself) in some individuals. These complications are uncommon, but they are the reason clinicians take coxsackievirus infections seriously even when the presenting illness looks straightforward.
Orchitis, a painful inflammation of the testes, is another recognized complication that can occur in boys and men during or shortly after an episode of pleurodynia. It is not common, but it is uncomfortable enough to warrant mentioning. In newborns, enteroviral infections of any kind are more dangerous simply because the infant immune system is less equipped to contain them, and neonatal myocarditis from group B coxsackieviruses carries real risk.
For the typical older child or adult, though, the complication that matters most is probably practical: missing work or school for a week or more because the pain is too intense to function normally. The episodic spasms can be genuinely debilitating even when the underlying condition poses no long-term threat.
Treatment and Recovery
There is no antiviral medication that targets the coxsackieviruses or echoviruses responsible for pleurodynia. Treatment is entirely supportive. Nonsteroidal anti-inflammatory drugs like ibuprofen are the mainstay for managing pain and bringing down fever. Warm compresses applied to the chest wall can help between spasms. Rest is important, both because physical exertion tends to trigger pain episodes and because the body needs time to clear the virus.
Most people improve substantially within four to seven days, though some experience a relapsing course in which the pain fades and then returns over a period of one to three weeks. A true relapse, where the spasms come back after days of feeling well, is disconcerting but not dangerous. It simply reflects the time the immune system needs to fully suppress viral replication in the affected muscles.
The main practical advice for someone recovering from pleurodynia is straightforward: stay hydrated, treat pain aggressively enough to breathe comfortably (shallow breathing from pain avoidance can itself cause problems), and see a doctor if symptoms worsen rather than improve after the first week, or if new symptoms like a stiff neck, testicular swelling, or persistent vomiting develop. Those would raise concern for one of the rarer complications.
Preventing Spread in Group Settings
Because enteroviruses are transmitted through contaminated hands, surfaces, and shared food or drink, prevention comes down to basic hygiene. Handwashing after using the bathroom and before eating remains the single most effective measure. For sports teams and summer camps, the football-outbreak investigation makes the case clearly: shared water bottles and communal ice chests are efficient vehicles for spreading the virus. Individual water containers are a simple fix.10JAMA. Pleurodynia Among Football Players at a High School
There is no vaccine against coxsackieviruses. Researchers have explored the idea, particularly because of the cardiac complications these viruses can cause, but no vaccine has reached clinical use. In the absence of a vaccine, the emphasis stays on interrupting transmission: clean hands, separate drinking containers, and keeping symptomatic individuals away from communal settings during the first few days of illness, when viral shedding is highest.
A Disease That Keeps Surprising Clinicians
Pleurodynia occupies an unusual place in modern medicine. It was well known during the mid-twentieth century, when large epidemics drew attention and prompted detailed clinical descriptions. As those big outbreaks became less frequent, the condition slipped out of mainstream clinical awareness. Sporadic cases still appear regularly, but they tend to be diagnosed late or not at all because the illness is simply not on the radar.
One case review described Bornholm disease explicitly as “a forgotten entity” and argued that physicians’ unfamiliarity with it leads to unnecessary and expensive investigations when patients present with its characteristic symptoms.11PubMed Central. Unusual cause of chest pain, Bornholm disease, a forgotten entity; case report and review of literature The condition has not become rare so much as it has become rarely recognized. Enteroviruses continue to circulate widely, and pleurodynia cases continue to appear, especially in summer and early fall. The gap is in diagnosis, not in disease burden.
There is also the question of whether pleurodynia-like presentations are sometimes triggered by other infectious or inflammatory events. At least one case report has described pleurodynia occurring after a COVID-19 vaccine, raising the possibility that the clinical syndrome of episodic chest-wall pain can occasionally be provoked by immune activation beyond classic enteroviral infection.12PubMed Central. A Rare Case of Pleurodynia After the COVID-19 Vaccine Whether such cases share the same muscle-level pathology as virus-driven pleurodynia or represent something distinct remains unclear, but they add another layer to an illness that already has a talent for catching people off guard.
