Sealed injection can effectively relieve the severe pain caused by costochondritis, while the cause of costochondritis is mainly infection, strain, etc., mainly through antibiotics, anti-inflammatory and analgesic drugs and surgery for treatment, so closed injection can not cure costochondritis. For the treatment of costochondritis caused by infection, antibiotics such as penicillin and cephalosporin can be used, and for the costochondritis that is not well treated by antibiotics, surgery can be used. For patients with obvious pain and poor symptomatic treatment, closed injections can be used, but closed injections can only relieve symptoms, not cure costochondritis. If you suffer from costochondritis, you should seek medical treatment in a timely manner, and the relevant drugs should be used under the guidance of a doctor.
