Individuals who experience joint inflammation, such as synovitis, osteoarthritis, bursitis, gouty arthritis, tendinitis, rheumatoid arthritis, or muscle trigger points, may be able to attain relief through the use of cortisone shots. Also referred to as corticosteroid injections or steroid injections, these injections work to reduce joint inflammation, ultimately minimizing swelling, heat, and redness, and alleviating joint pain. The mechanism of action for these injections involves the inhibition of arachidonic acid release from phospholipids, thereby reducing the formation of prostaglandins, which contribute to the inflammatory process.
