Chest pain is commonly associated with nonspecific costochondritis, a nonspecific, nonsuppurative inflammation of the rib cartilage that presents as a self-limiting disease with limited pain with swelling. It is most commonly seen in young adults and is more common in women than men. The etiology is not clear. The possible causes are as follows: viral infection, chronic strain on the ligaments of the thoracic rib joints, dystrophy of the rib cartilage, and trauma. The disease often occurs during the change of seasons between winter and spring and between autumn and winter, and it starts slowly. The main symptom of costochondritis is localized pain, which can be seen as a swelling, enlargement, and pressure pain in the involved cartilage, with varying degrees of severity and relatively fixed pain points. The pain can be exacerbated by excessive thoracic movement caused by coughing, deep breathing, or expansion of the chest wall. Some patients may have involvement pain and radiating pain. The skin surface is generally free of inflammatory changes such as redness, swelling and heat. The prevalent site is 2 to 4 rib cartilages, most cases only invade a single rib cartilage, while some cases have more than 2 or multiple ribs bilaterally. The main diagnostic basis is clinical symptoms and local signs. It should be differentiated from rib fractures, coronary artery disease, and tumors. Although the rib cartilage cannot be visualized on X-ray and the lesion cannot be detected on chest X-ray, it helps to exclude intra-thoracic lesions, chest wall tuberculosis, and rib osteomyelitis. The disease has a tendency to heal on its own, usually lasting 2 to 3 months, and can resolve or disappear on its own. However, some patients have recurrent episodes, sometimes good and sometimes bad, sometimes light and sometimes heavy, and it can be prolonged for months or even years. Symptomatic treatment is the main focus: 1. proper rest, reduce upper limb and chest activities. 2. 2, local physiotherapy, hot compresses, severe pain application of non-steroidal anti-inflammatory and analgesic drugs, or compound betamethasone injection plus lidocaine local closure. 3.For a very small number of patients with severe local pain, the above treatments are ineffective, seriously affecting the life and work of patients and causing a certain mental burden, or those suspected of having malignant tumors, surgical removal can be considered.
