A joint injection is a medical procedure where medication is injected directly into a joint space to relieve pain and inflammation. This is often used for conditions such as arthritis, bursitis, and tendonitis. The injection typically contains a local anesthetic, corticosteroids, or hyaluronic acid, depending on the specific issue being treated. The injection is usually done in a clinical setting and may involve imaging guidance (like ultrasound or X-ray) to ensure accuracy.

Here are some key points:

1. Joint injections can provide rapid relief from pain and swelling, helping to improve mobility.
2. Corticosteroids, commonly called cortisone or steroids, can reduce inflammation in the joint, offering longer-lasting relief.
3. Hyaluronic Acid or Visco- supplement injections are commonly used for osteoarthritis. This substance helps lubricate the joint and may improve function.

While generally safe, potential side effects can include infection, bleeding, or temporary increased pain at the injection site. Multiple injections may be needed for ongoing relief.
