Infectious costochondritis can be treated with medication, surgery, etc. The medication should be used according to the doctor’s prescription. 1. Drug treatment: early treatment with sensitive antibiotics, such as cefuroxime. Patients who need surgery need to use antibiotics at an early stage and in sufficient quantity before surgery. If the pain is severe, non-steroidal anti-inflammatory drugs can be used, such as ibuprofen, etc. Steroid hormones can also be used for localized closed treatment, such as procaine. 2. Surgery: If antibiotic treatment is not effective, surgery can be used to remove the diseased rib cartilage completely. After surgery, sensitive antibiotics are used to fight infection for 1-2 weeks according to the drug sensitivity test. It is recommended that patients with infected costochondritis should go to regular hospitals in time and take active treatment to avoid delaying their condition.
