You’re not alone. Cortisone injections are one of the most common treatments for inflammatory conditions in Australia, helping thousands of people manage pain and get back to their daily activities. These powerful anti-inflammatory injections can provide significant relief for various musculoskeletal problems, from arthritic knees to frozen shoulders. Yet, despite their widespread use, many people feel uncertain about what the procedure actually involves.
We will walk you through everything you need to know about cortisone injections. We’ll cover how they work, what happens during the procedure, and what you can expect in the days and weeks that follow. Whether you’re considering your first injection or preparing for a repeat treatment, you’ll find all the information you need to feel confident and informed. Let’s get stuck into the details.
What Are Cortisone Injections and How Do They Work?
Cortisone injections contain corticosteroids, which are synthetic versions of hormones naturally produced by your adrenal glands. These medications work by reducing inflammation at the injection site, which in turn decreases pain and improves function. Unlike oral steroids that affect your entire body, injections deliver medication directly to the problem area.
The injection typically contains a combination of corticosteroid and local anaesthetic. The anaesthetic provides immediate but temporary pain relief, while the corticosteroid takes a few days to kick in. This targeted approach means you get maximum benefit at the affected area with minimal systemic effects.
Common Conditions Treated with Cortisone Injections
Cortisone injections are used to treat a wide range of inflammatory conditions. These include osteoarthritis, rheumatoid arthritis, bursitis, tendinitis, and carpal tunnel syndrome. They’re also effective for conditions like plantar fasciitis, frozen shoulder, and tennis elbow. Your doctor will assess whether this treatment is appropriate for your specific situation.
Before Your Cortisone Injection
How to Prepare for a Cortisone Injection
Preparation for a cortisone injection is generally straightforward. Your doctor will review your medical history and may request imaging tests to pinpoint the exact location of the problem. It’s important to inform them about any medications you’re taking, particularly blood thinners.
On the day of your appointment, wear loose, comfortable clothing that allows easy access to the injection site. You don’t need to fast beforehand, and most people can drive themselves to and from the appointment.
What Should You Avoid Before a Cortisone Injection?
Your doctor may ask you to stop taking certain medications before the procedure. Blood-thinning medications like aspirin or warfarin might need to be paused to reduce the risk of bleeding. However, never stop taking prescribed medication without consulting your doctor first.
Avoid alcohol for at least 24 hours before your injection. Plus, if you’re feeling unwell or have signs of infection, let your clinic know. The procedure may need to be rescheduled.
Questions to Ask Your Doctor Before Treatment
Before proceeding, consider asking your doctor these key questions:
- How many injections might I need?
- What results can I realistically expect?
- Are there any alternatives I should consider?
- What are the risks specific to my situation?
- How long should I wait before resuming normal activities?
Who Should Not Get Cortisone Injections?
Cortisone injections aren’t suitable for everyone. People with active infections, uncontrolled diabetes, or bleeding disorders may need to avoid them. Pregnant women should discuss the risks with their healthcare provider. If you’ve had multiple injections in the same area, your doctor may recommend alternative treatments to avoid potential complications.
During the Procedure: What Happens Step by Step
What Does the Injection Process Involve?
The procedure is typically performed in your doctor’s clinic or a specialist’s rooms. First, the area is cleaned thoroughly with antiseptic solution. Your doctor may use ultrasound guidance to make sure the needle reaches the exact right spot, which improves accuracy and effectiveness.
The skin might be numbed with a cold spray or local anaesthetic cream. Then, the needle is inserted, and the medication is slowly injected. Some practitioners withdraw a small amount of fluid first if there’s swelling in the joint.
Does a Cortisone Injection Hurt?
Let’s be honest, you’ll likely feel some discomfort. Most people describe it as a sharp pinch followed by a feeling of pressure. The local anaesthetic in the injection mixture usually kicks in quickly, providing immediate numbness. Pain levels vary depending on the injection site, with some areas being more sensitive than others.
Taking slow, deep breaths during the procedure can help you stay relaxed. The anticipation is often worse than the actual experience.
How Long Does a Cortisone Injection Take?
The entire appointment usually takes around 15 to 30 minutes. The actual injection itself only lasts a few seconds to a minute. Most of the time is spent on preparation, cleaning the area, and positioning.
After Your Cortisone Injection
Immediate Aftercare: The First 24-48 Hours
Once the injection is complete, you might be asked to rest for a few minutes before leaving. Apply ice to the area for 15 to 20 minutes several times during the first day to reduce any swelling. Keep the injection site clean and dry for at least 24 hours.
Rest the affected area as much as possible during the first couple of days. Avoid strenuous activities, heavy lifting, or anything that puts stress on the treated joint.
How Long Does It Take for a Cortisone Injection to Work?
You may notice immediate relief from the local anaesthetic, but this wears off within a few hours. The corticosteroid typically begins working within 2 to 7 days. Some people experience significant improvement within 48 hours, while others may need to wait a full week.
Maximum benefit usually occurs around two weeks post-injection. If you haven’t noticed any improvement after three weeks, contact your doctor.
What Should You Not Do After a Cortisone Injection?
For the first 48 hours, avoid:
- Hot baths, saunas, or swimming pools
- Strenuous exercise or heavy lifting
- Putting excessive pressure on the injection site
- Drinking alcohol in excess
Your doctor will provide specific guidance based on the injection location. For example, after a knee injection, you might be advised to avoid running for several weeks.
Managing the Cortisone Flare: Is Temporary Pain Normal?
Some people experience a cortisone flare within the first 24 to 48 hours. This is a temporary increase in pain and swelling caused by the crystalline structure of the medication. It’s completely normal and usually resolves within a couple of days.
Ice packs and over-the-counter pain relief can help manage this discomfort. If the pain is severe or lasts longer than 72 hours, contact your healthcare provider.
Cortisone Injection Side Effects and Risks
Common Side Effects to Expect
Most side effects are mild and temporary. These include:
- Pain or swelling at the injection site
- Temporary facial flushing
- Slight elevation in blood sugar levels (important for diabetics)
- Temporary skin lightening at the injection site
Less common side effects include infection, nerve damage, or thinning of nearby cartilage.
Are Cortisone Injections Safe?
When administered by a qualified healthcare professional, cortisone injections are generally considered safe. The risks are relatively low, especially when injections are spaced appropriately. Your doctor will weigh the benefits against potential risks for your specific situation.
How Many Cortisone Injections Can You Have?
There’s no magic number, but most doctors recommend limiting injections to three or four per year in the same area. Too many injections can potentially weaken tendons and cartilage over time. Your healthcare provider will monitor your response and adjust treatment accordingly.
Long-Term Considerations
How Long Do Cortisone Injections Last?
The duration of relief varies significantly between individuals. Some people experience relief for several months, while others may only notice improvement for a few weeks. Factors like the underlying condition, injection site, and individual response all play a role.
When Should You Consider Another Injection?
If your symptoms return after a period of relief, another injection might be appropriate. However, your doctor will consider the timing carefully. Most practitioners recommend waiting at least three months between injections in the same area.
Alternatives to Cortisone Injections
If cortisone injections aren’t suitable or haven’t provided adequate relief, alternatives include:
- Physiotherapy and exercise programs
- Hyaluronic acid injections
- Platelet-rich plasma (PRP) therapy
- Oral anti-inflammatory medications
- Surgical intervention (for severe cases)
Consclusion
Cortisone injections can be a game-changer for people struggling with inflammatory conditions and persistent joint pain. They offer targeted relief that can significantly improve quality of life and help you return to activities you enjoy. Understanding what to expect before, during, and after treatment helps you feel prepared and confident.
Remember, cortisone injections work best as part of a comprehensive treatment plan. Combining injections with physiotherapy, lifestyle modifications, and appropriate rest often yields the best long-term results. Don’t hesitate to discuss all your options with your healthcare provider.
