After the cause is clearly identified, if there is localized costochondritis, the patient needs to be kept at bed rest and treated with anti-inflammatory, anti-swelling, and pain-relieving medications. In addition to this, you can also apply ointment such as blood circulation and pain relief cream or wound and wet pain relief cream to the painful area.3.

If there is a local focal point of infection, sensitive antibiotics should be applied for treatment, and some of them may require debridement surgery. 5. If the bulge is caused by a large amount of localized pleural effusion, a thoracic puncture or closed drainage of the thorax may be required for treatment.
