TL;DR: While Costochondritis and the related Tietze Syndrome are common causes of chest pain in clinical settings, exact prevalence data is difficult to determine because many cases are self-limiting and go undiagnosed. Current estimates suggest that Costochondritis accounts for approximately 10% to 30% of all pediatric chest pain cases and is frequently encountered in primary care and emergency departments for adults. Is Costochondritis considered a rare disease? In the medical community, Costochondritis is generally categorized as a common musculoskeletal condition rather than a rare disease.

In the medical community, Costochondritis is generally categorized as a common musculoskeletal condition rather than a rare disease. However, Tietze Syndrome, a specific inflammatory variant characterized by visible swelling of the costochondral joints, is significantly less frequent and is often classified as a rare disorder. Because both conditions involve inflammation of the cartilage that connects a rib to the breastbone, they are often grouped together in clinical research, which complicates the ability to provide a precise global prevalence rate. At DiseaseMaps.org, 171 community members have connected to share their experiences with Costochondritis / Tietze Syndrome, highlighting that while the condition is common, the patient journey can still feel isolating.
The demographic distribution of these conditions provides insight into who is most affected. While data varies, clinical observations show the following trends:
Accurate epidemiological data for Costochondritis is hampered by several factors. Many individuals experience mild, transient chest pain that resolves without medical intervention, meaning these cases are never recorded in healthcare databases. Furthermore, because chest pain is a "red flag" symptom, patients are often evaluated to rule out life-threatening cardiac or pulmonary conditions. Once serious illness is excluded, the diagnosis of Costochondritis is often made clinically, but it may not always be coded specifically in electronic health records. Consequently, the true incidence of Costochondritis / Tietze Syndrome is likely much higher than the number of documented clinical encounters.
The primary challenge in mapping the prevalence of Costochondritis / Tietze Syndrome is the lack of a definitive diagnostic test. Diagnosis is primarily one of exclusion, meaning doctors must first rule out heart attacks, pericarditis, or other serious thoracic issues. Because the symptoms of Costochondritis mimic cardiac events, many patients undergo extensive and unnecessary testing, which can lead to misdiagnosis or diagnostic delay. Understanding the prevalence is further complicated by the fact that Tietze Syndrome presents with localized swelling (edema), whereas general Costochondritis does not, leading to inconsistent reporting across different medical studies.
