In the case of a patient with costochondritis, it usually takes about 2 weeks for the symptoms to resolve significantly. Because costochondritis is a sterile inflammatory disease, after the onset of the disease the sterile inflammation stimulates the surrounding soft tissues, resulting in inflammatory edema, which generally peaks at 72 hours. Then, the inflammatory edema begins to gradually subside and absorb, and generally in about 2 weeks, the inflammatory edema will completely subside, and the patient’s clinical symptoms will be significantly relieved. Therefore, after the occurrence of chondromalacia, it is necessary to pay more attention to keep warm, avoid getting cold, avoid stimulation by pressing the inflammatory site, and apply non-steroidal anti-inflammatory drugs to counteract the sterile inflammation of the costochondritis site and promote the recovery of costochondromalacia.
