What is a common presenting symptom of costochondritis?

Localized chest pain is a hallmark symptom of costochondritis, which refers to inflammation of the cartilage connecting the ribs to the sternum. This pain is typically sharp and can be reproduced by pressing on the affected area, making it distinct from pain caused by heart conditions or gastrointestinal issues. Patients may describe the pain as worsening with movement, deep breathing, or changes in position. This localized nature differentiates it from other chest pain conditions, ensuring that it is identifiable.

Severe abdominal pain would not be associated with costochondritis as it typically pertains to gastrointestinal or other abdominal issues. Similarly, radiating pain in the arm is more indicative of cardiac problems, particularly angina or myocardial infarction. Nausea and vomiting are also not common in costochondritis and suggest gastrointestinal disturbances rather than musculoskeletal conditions. Thus, localized chest pain is the correct choice that aligns with the typical presentation of this condition.
