Corticosteroids are powerful anti-inflammatory medicines that help reduce swelling and inflammation in the affected joint, which in turn alleviates pain. This treatment option is typically used for arthritis, tendonitis, and other inflammatory conditions. Corticosteroid, or "cortisone", injections can provide quick relief, often noticeable within a few days, and can last several weeks to several months, depending on the condition and patient.
