Cortisone injections are commonly used to reduce inflammation and relieve pain from joint or soft tissue injuries. They contain corticosteroids, which mimic the body’s natural anti-inflammatory hormones. These injections are often administered directly into the affected area, such as a knee or shoulder. Relief may be felt within a few days and can last from weeks to months. Cortisone injections are typically part of a broader treatment plan, including rest, physical therapy, or other interventions to support long-term healing and prevent further injury.
