Pleuralgia is a medical term that refers to pain in the pleura, which is the thin tissue that lines the lungs and chest cavity. Although the term pleuralgia is specific to this type of pain, there are other terms and phrases that can be used to describe similar conditions. Some common synonyms for pleuralgia include chest pain, chest wall pain, pleurisy, costochondritis, and intercostal neuralgia. These terms may describe pain that is caused by inflammation, infection, injury, or nerve damage in the chest area. While these conditions can cause discomfort and difficulty breathing, they can often be treated with medication and other therapies.
