For patients with costal chondromalacia, there is usually no significant relief of symptoms for about 2 weeks. Because chondromalacia of the ribs is a sterile inflammatory disease, the onset of sterile inflammation stimulates the surrounding soft tissues and inflammatory edema occurs. The inflammatory edema usually reaches its peak in 72 hours, after which it begins to gradually subside and resorb, and the patient’s symptoms will be significantly relieved when the inflammatory edema has completely subsided in about 2 weeks. Therefore, after the occurrence of costochondritis, it is important to keep warm, avoid getting cold, avoid stimulation by pressing the inflammatory site, and apply non-steroidal anti-inflammatory drugs to counteract sterile inflammation at the site of costochondritis and promote the recovery of costochondritis.
