Cortisone Shot Pain: Why Does It Get Worse After the Injection?
Cortisone shot pain can temporarily worsen due to a temporary cortisone flare, which can cause intense localized discomfort and swelling near the injection site for several hours. This response occurs due to initial joint irritation before the steroid begins its therapeutic action.
At Total Orthopedics & Sports Medicine, our specialists assess your affected joint, identify underlying causes, and create a personalized treatment plan to reduce inflammation and relieve pain. Throughout your treatment, our team is committed to guiding you through recovery and helping you return to comfortable movement as soon as possible.

Why Do Some People Experience Pain Flare-Ups After a Cortisone Injection?
Some people experience pain flare-ups after a cortisone injection because the medication can temporarily irritate the treated area before its anti-inflammatory effects begin. In some cases, your immune system may respond with steroid crystals that can temporarily irritate the joint and trigger inflammation.
According to ePainAssist, a post-injection pain flare, also known as a steroid flare, occurs in approximately 1% to 30% of patients after a corticosteroid injection. These flare-ups typically begin within 6 to 48 hours after the injection and usually resolve within 1 to 3 days. However, you should contact your healthcare provider if the pain is severe, lasts longer than 2 weeks, worsens over time, or is accompanied by redness, fever, or increasing swelling.
Can an Allergic or Sensitivity Reaction Trigger a Cortisone Flare Up?
Yes, an allergic or sensitivity reaction can trigger a cortisone flare-up in some people. This cortisone flare-up occurs when your immune system reacts to the corticosteroid, the local anesthetic, or other components in the injection. This reaction can cause temporary swelling, redness, and increased pain at the injection site.
However, allergic reactions to corticosteroid injections are rare. According to UpToDate, allergic reactions occur in only about 0.1% of cases, meaning that most reactions are linked to preservatives or the anesthetic, rather than the steroid itself. Additionally, factors such as sensitivity to specific steroids, a history of previous reactions, or overactive immune activity can increase the chance of a flare-up.
How Can Overuse of the Joint After the Injection Lead to Worsening Pain?
After the injection, the local anesthetic wears off quickly, which makes the joint more sensitive before the steroid takes effect. As a result, any excess movement during this early recovery period can easily irritate the joint and surrounding tissues.
Moreover, activities such as running, lifting, or twisting place mechanical stress on an already inflamed area and may trigger additional swelling and discomfort. That’s why you should rest the jointand avoid heavy exercise for 1–2 days to support proper healing.
Can Injection Placement Affect Pain or Results?
Yes, improper injection placement can worsen pain if the medication is placed in the wrong tissue or irritates nearby joint structures. Depending on the condition being treated, cortisone may be injected into a large joint, such as the knee, or around other affected tissues. But poor needle placement can also lead to bleeding, swelling, or increased soreness shortly after the procedure.
Other than that, if the technique is inaccurate, the medication may not reach its intended target, which reduces the overall effectiveness of the cortisone. According to Guideline Central, ultrasound-guided injections provide more accurate intra-articular needle placement than landmark-based techniques and may lower the risk of injection-related tissue damage. Therefore, you should receive cortisone injections from a trained healthcare provider who uses proper technique and, when needed, imaging guidance.
When Should You Seek Medical Attention for Post-Injection Pain?
Seek medical attention if post-injection pain is severe, spreads to nearby joints or tissues, or lasts longer than expected. Although serious side effects are uncommon, you should contact an orthopedic specialist if you develop redness, warmth, fever, or increasing swelling. The following symptoms may indicate an infection or another complication and require medical attention:
- Significant stiffness or locking
- Rapidly increasing bruising
- Difficulty bearing weight
- Persistent numbness or tingling
- Drainage around the injection site
Rare but serious steroid-related complications can also occur. For example, osteonecrosis (avascular necrosis) involves the death of bone tissue due to reduced blood supply. It has been associated with corticosteroid exposure, particularly with higher or prolonged systemic steroid use.
At Total Orthopedics & Sports Medicine, our pain management team carefully assesses your symptoms to determine whether it’s a temporary cortisone flare or a serious complication. We then provide personalized care to reduce pain, swelling, and stiffness, while supporting proper joint healing. Call 855-321-6784 today to schedule your consultation.
What are the Signs of a Cortisone Flare Up VS a Complication?
A cortisone flare-up causes temporary pain, warmth, and swelling within 24 to 48 hours. These cortisone flare symptoms are short-term and typically improve with ice and rest. In contrast, complications often involve progressive pain, systemic symptoms such as fever, drainage from the injection site, or neurologic changes.
In addition to temporary pain and swelling, a cortisone flare may cause joint stiffness, mild tenderness around the tendon, or sensitivity during specific movements. Some people may also notice fluid buildup near the joint or slight redness on the skin, which typically goes away within a few days without medical treatment. But progressive redness, warmth, swelling, fever, or worsening pain requires assessment.
Here are some other differences that can help you distinguish a normal cortisone flare from signs of a possible complication:
| Normal Cortisone Flare | Possible Complication |
|---|---|
| Begins shortly after the injection | May develop or progress after the injection |
| Symptoms gradually improve | Symptoms worsen over time |
| Usually settles within a few days | Persists longer than expected |
| Remains localized to the treated area | Symptoms may spread beyond the treated area |
| No fever | Fever may develop |
How Long Does Post-Injection Soreness Typically Last?
Patients commonly experience mild soreness for one to four days after an injection, particularly within the first 24 to 48 hours. In rare cases, soreness can last up to a week, especially if you experience a cortisone flare from steroid medication. However, if pain persists for longer than a week or you notice redness, warmth, or a fever, seek medical attention promptly.
In addition, the duration of soreness can vary based on the following factors:
- The joint treated
- The injection depth
- How your body responds to the medication
Other factors, such as the underlying condition and the amount of inflammation present before the injection, may also influence how long discomfort lasts. To support recovery, rest the joint, apply ice as needed, and avoid strenuous activity. You can also use over-the-counter pain relievers to help manage discomfort during the first few days after the injection. These steps may help reduce temporary soreness during recovery.
Why Does Pain Come Back When a Cortisone Shot Wears Off?
Pain can come back when a cortisone shot wears off because the injection reduces inflammation and pain, but does not always correct the underlying condition causing your symptoms. As the medication’s effects gradually fade, inflammation may return, especially if joint damage, arthritis, or another ongoing orthopedic problem remains.
Additionally, the duration of relief can vary depending on the condition being treated, the severity of the problem, and how your body responds to the injection. Some patients may feel relief after the medication begins reducing inflammation, but the duration of that improvement can vary from person to person. If symptoms repeatedly return after temporary relief, your orthopedic specialist may reassess the joint to determine whether a different treatment option is appropriate.
What Is The Next Step If A Cortisone Shot Doesn’t Work?
If a cortisone shot doesn’t work, you may need additional imaging, alternative medications, or activity modification to manage ongoing pain. In some cases, repeated cortisone shots or other steroid injections are considered, but only after assessing the most common side effects, increased risk factors, and long-term effects on the affected joint.
Additionally, your healthcare provider may recommend nonsurgical options, such as bracing or regenerative injections. Your doctor may also review previous potential side effects from cortisone, such as temporary facial flushing or difficulty sleeping, before recommending another injection.
Depending on the underlying condition, they may also consider platelet-rich plasma or gel injections as an alternative to cortisone. Besides that, doctors do not administer more than three or four injections in the same area within a year to reduce cumulative risks. They generally limit cortisone injections to every 3–6 months.

FAQs
What Is Cortisone?
Cortisone is a corticosteroid medication that mimics cortisol produced by the adrenal glands. Cortisone works by reducing inflammation in joints or in fluid-filled sacs called bursae. Once cortisone takes effect, it may relieve pain, but it is not a long-term solution.
What Happens When A Cortisone Shot Hits A Nerve?
When a cortisone shot hits a nerve, you may feel sudden, sharp, or intense pain during or shortly after the injection. This reaction occurs because the needle or medication irritates the nerve. In most cases, the irritation is temporary and improves as the nerve settles.
What Are The Symptoms Of Joint Infection After A Cortisone Injection?
Joint infection after a cortisone injection typically causes severe, worsening joint pain. These symptoms are also accompanied by swelling, redness, and warmth around the affected joint. In addition, fever, chills, increasing stiffness, difficulty bearing weight, or drainage from the injection site may develop.
When Should Pain Relief Start After a Cortisone Shot?
Pain relief after a cortisone shot may begin within a few days once the medication reduces inflammation. Before the cortisone takes effect, some patients may experience temporary worsening pain from a cortisone flare. If you do not feel relief or your pain continues to worsen, contact your healthcare provider.
How Long Does Post-Injection Pain Usually Last?
Post-injection pain usually improves within a few days. In some cases, soreness can persist for several weeks, particularly if a cortisone flare develops. But the exact duration depends on factors such as the joint injected, the corticosteroid dose, and your body’s response to the medication.
Should I Ice or Rest If the Pain Increases After the Shot?
Yes, you should apply ice and rest the joint if pain increases after a cortisone shot. Ice may help reduce temporary pain and swelling, while rest limits stress on irritated tissues as the medication begins to work. During this time, avoid strenuous activity for at least 24 to 48 hours. However, if pain worsens rather than improves, seek medical attention promptly.
Can Stress Or Anxiety Make Post-Injection Pain Feel Worse?
Yes, stress and anxiety can worsen the post-injection pain because they increase muscle tension and the body’s immune response. As a result, the affected joint may feel more sensitive, and the discomfort may persist for a longer period. By practicing relaxation techniques, controlled breathing, and gentle movement, you can ease this tension and support a smooth recovery.
Is Warmth Or Burning After A Cortisone Shot Normal?
Yes, a mild warmth or burning sensation after the cortisone shot is normal. This reaction often occurs as the medication spreads through the joint and surrounding tissues. It is a common, short-term response that gradually eases as the cortisone begins to reduce inflammation and provide pain relief.
