Costochondritis usually takes about two or three weeks to heal, depending on the severity of the patient’s costochondritis. If the patient’s costochondritis is mild, it usually takes about two weeks to get well after treatment. If the patient’s costochondritis is more serious, and if the patient does not pay attention to diet and over-exercise during the recovery period, the reinfection occurs, the recovery time after treatment may take about three weeks. Patients with costochondritis should rest more, avoid strenuous activities, and use hot towels to apply warm compresses during the recovery period to reduce pain. At the same time pay attention to quit smoking and drinking, pay attention to keep warm to avoid catching cold, try not to sit for a long time, to avoid external gravity damage to the chest.
