What Is a Cortisone Injection?
A cortisone injection is a powerful anti-inflammatory treatment used to reduce pain and swelling in specific areas of the body. It contains a corticosteroid medication and is often administered directly into joints, tendons, or soft tissues.
Common Conditions Treated with Cortisone Injections
Cortisone injections are commonly used to treat:
Arthritis (especially osteoarthritis and rheumatoid arthritis)
Tendonitis and bursitis
Carpal tunnel syndrome
Plantar fasciitis
Shoulder impingement and rotator cuff issues
Back pain caused by inflammation
How Does a Cortisone Injection Work?
Cortisone works by reducing inflammation at the targeted site. Once injected, it suppresses the immune response that leads to swelling, redness, and pain. The effects can begin within a few days and last from weeks to several months.
What to Expect During the Procedure
The procedure is typically quick and performed in a clinic. Here's what to expect:
The area is cleaned and may be numbed with a local anesthetic.
A needle is inserted to deliver the cortisone directly into the inflamed area.
You may feel pressure or mild discomfort during the injection.
Benefits of Cortisone Injections
Rapid pain relief
Reduced inflammation
Improved mobility and function
Avoidance or delay of surgery
Possible Side Effects and Risks
While cortisone injections are generally safe, potential side effects include:
Temporary increase in pain after injection (flare-up)
Skin thinning or discoloration at the injection site
Elevated blood sugar in diabetic patients
Joint infection (rare)
Weakening of tendons with repeated use
Aftercare and Recovery Tips
After the injection:
Rest the treated area for 24–48 hours.
Avoid heavy lifting or intense activity.
Use ice to reduce swelling if necessary.
Follow your doctor’s instructions carefully.
How Often Can You Get Cortisone Injections?
Most doctors limit cortisone injections to no more than 3-4 times per year in the same area to prevent tissue damage. The frequency depends on your condition and how your body responds to the treatment.
When to Consider a Cortisone Injection
You may be a candidate for cortisone injections if:
Pain persists despite physical therapy or oral medications
Inflammation interferes with daily activities
You’re not ready for surgery
Conclusion
Cortisone injections can be a highly effective way to manage pain and inflammation for various conditions. Always consult with your healthcare provider to determine if this treatment is right for you.
