The management of inflammation of the psoas muscle generally differs depending on the specific cause of the inflammation of the psoas muscle. The two most common causes of inflammation of the psoas muscle are localized aseptic inflammation or localized suppurative inflammation. For local sterile inflammation, the best treatment includes symptomatic oral administration of non-steroidal anti-inflammatory drugs such as Aceclofenac, Diclofenac or Celecoxib, either of which can be taken. The local sterile inflammation can be quickly reduced by taking them continuously for 1 week according to the dosage instructions. In addition, local hot compresses and physiotherapy can also be used in conjunction with the treatment. For lumbar myositis caused by septic inflammation, symptomatic treatment such as intravenous fluids or oral antibiotics can be given.
