Costochondritis is generally referred to as costochondritis, which is an inflammatory lesion occurring in the area of rib cartilage, divided into non-infectious costochondritis and infectious costochondritis, which is mainly manifested as swollen and bulging rib cartilage area with localized pain and pressure, and the treatments for different types of costochondritis are also different. The costal cartilage is located at the junction of ribs and sternum, trauma, chronic strain injury, nutritional disorders of the costal cartilage can lead to non-infectious costal chondritis; tuberculosis bacillus, typhoid bacillus and other pathogenic bacteria can be infected with costal cartilage through the blood circulation, and the surgery of the costal cartilage area can also lead to the costal cartilage being directly infected, resulting in infectious costal chondritis. The main manifestations of costochondritis are redness, swelling, heat, pain, and elevated body temperature in the local costochondral area. If the disease is prolonged, the local soft tissue necrosis may form abscess, and after the abscess breaks down, the local sinus tract will appear, and the pale costochondral bone can be seen to be exposed at this time. Treatment, for non-infectious costochondritis only need to give ibuprofen, diclofenac sodium, procaine and so on for analgesic treatment; for infectious costochondritis also need to use antibiotics, such as oxfloxacin, cefoperazone and so on to control the infection. If the diagnosis of costochondritis is confirmed, please follow the doctor’s instructions for treatment.
