Cortisone Must Be Given Appropriately
Doctors often inject cortisone-type medications into painful, damaged joints. Single injections can relieve pain and swelling and appear to be safe, but repeated injections given too soon or too often can damage joints and delay healing.
When Cortisone Injection Done Safely, Benefit Is Huge
Since people can be crippled by arthritis, and a single cortisone injection into a damaged knee joint, for example, can allow an arthritic to walk without pain for many weeks -- cortisone-type drugs continue to be used to reduce swelling, lessen pain, and allow patients to return to normal daily activities.
Rule of Thumb for Cortisone Injection
Cortisone injections vary, and both short and long acting preparations are used, depending on the patient's needs. The duration of effectiveness depends on the type of cortisone injected, and how long the patient rests the joint after injection. A good general rule to follow is to give no more that 2-3 injections into the same joint in any given year, and ideally, rest the joint for 1 week after each injection.
