Cortisone shots are a common medical treatment that alleviates pain and reduces inflammation. These injections deliver a corticosteroid, a medication that mimics the natural hormone cortisol. Corticosteroids work by temporarily decreasing the immune system’s activity to lessen inflammation, reducing associated pain and swelling. Many individuals receiving this treatment wonder about the timeline for experiencing relief.
Initial Post-Injection Experience
Immediately following a cortisone shot, some individuals experience a temporary increase in pain or discomfort at the injection site. This is often called a “cortisone flare.” This temporary worsening occurs because the injected medication can crystallize, irritating surrounding tissues. About one in five people experience this flare, which resolves within one or two days. Applying ice and resting the affected joint can help manage this discomfort.
When Relief Typically Begins
Immediate relief is often due to a local anesthetic mixed with the cortisone, providing numbing that wears off in a few hours. The cortisone’s anti-inflammatory effects take longer to manifest. Most patients notice pain relief within three to seven days after the injection. For some, significant reduction in inflammation and pain may take up to two weeks. The full benefits of the injection may not be felt until about six weeks post-injection.
Factors Affecting the Timeline
Several factors can influence how quickly an individual experiences relief from a cortisone shot. The specific condition treated plays a role; for instance, relief for tendinitis may differ from arthritis. The severity and chronicity of inflammation also impact the timeline, with more severe or long-standing cases potentially requiring longer for the shot to take effect. The injection’s location also influences relief, with larger joints sometimes experiencing faster effects than smaller, more sensitive areas. Individual patient response, corticosteroid dosage, and anesthetic inclusion also contribute to how quickly relief is felt.
What to Expect if Relief Doesn’t Occur
If expected relief does not materialize within a few weeks, contact a healthcare provider. Reasons for lack of relief include the pain not being primarily caused by inflammation, which cortisone targets. The injection might not have reached the precise inflamed area, especially if image guidance was not used. A severe condition might require a different intervention or multiple doses. The shot may simply not be effective for that individual, or the underlying problem requires a different treatment.
