Yuba City Advanced Imaging Center provides Steroid Injections for pain relief of the knee, hip, shoulder, ankle, elbow, and wrist.  Steroids are medications that treat inflammation.  Pain is decreased from Steroid Injections because the inflammation is diminished. By injecting steroids into a particular area of inflammation, very high concentrations of the medication can be given while keeping potential side-effects to a minimum. Steroid injections usually work within a few days, and the effects can last up to several months.  We use long-lasting steroid medication to maximize its effectiveness.
