Cortisone shots can sometimes cause temporary pain flare-ups before providing relief.
Understanding Cortisone Shots and Their Purpose
Cortisone shots are a common treatment used to reduce inflammation and relieve pain in joints, tendons, and soft tissues. These injections contain corticosteroids, synthetic drugs that mimic hormones naturally produced by the adrenal glands. Their primary function is to suppress inflammation, which often causes discomfort and swelling in affected areas.
Doctors frequently use cortisone injections for conditions like arthritis, bursitis, tendonitis, and other inflammatory disorders. The goal is to deliver a powerful anti-inflammatory agent directly to the problem site, minimizing systemic side effects compared to oral steroids.
While many patients experience significant relief after a cortisone shot, the process isn’t always straightforward. Some report increased pain immediately following the injection. This paradox raises an important question: can a cortisone shot make pain worse? The answer involves understanding how these injections work and the body’s response.
Why Can A Cortisone Shot Make Pain Worse Temporarily?
It might seem counterintuitive that an injection meant to reduce pain could initially worsen it. Yet, this phenomenon—often called a “cortisone flare”—occurs in roughly 10-20% of patients receiving the shot.
A cortisone flare happens when the steroid crystals irritate the tissue at the injection site. Instead of calming inflammation right away, these crystals can cause a sudden increase in irritation and discomfort. This reaction typically peaks within 24 to 48 hours post-injection.
The good news is that this flare is usually short-lived. After the initial spike in pain subsides, most patients notice significant improvement within several days to weeks as inflammation decreases.
Several factors influence whether someone experiences this flare:
- Injection technique: Poor placement or multiple needle passes can aggravate tissue.
- Type of corticosteroid used: Some formulations are more prone to causing irritation.
- Individual sensitivity: Patient-specific reactions vary widely.
Understanding this temporary setback helps patients set realistic expectations and avoid unnecessary alarm when discomfort spikes after treatment.
The Biological Mechanism Behind Cortisone-Induced Pain Flares
Corticosteroids work by blocking various inflammatory pathways at the cellular level. However, when injected as crystalline suspensions, these particles can physically irritate cells lining joints or soft tissues.
The crystals trigger immune cells like macrophages and neutrophils to release pro-inflammatory substances briefly before suppression kicks in. This transient immune activation leads to increased swelling and pain sensations.
Additionally, the injection itself causes minor trauma—needle penetration disrupts tissue integrity—which compounds irritation during initial hours post-injection.
Once corticosteroids dissolve into surrounding fluid and begin modulating gene expression related to inflammation, symptoms start fading. The anti-inflammatory effects usually become noticeable within 3-5 days but may take up to two weeks for full benefits.
Comparison of Common Corticosteroid Types Used
| Corticosteroid Type | Onset of Action | Risk of Flare |
|---|---|---|
| Methylprednisolone acetate (Depo-Medrol) | 1-3 days | Moderate |
| Triamcinolone acetonide (Kenalog) | 2-5 days | Moderate to High |
| Dexamethasone sodium phosphate (Decadron) | Within 24 hours | Low (more soluble) |
| Betamethasone acetate/phosphate (Celestone) | 1-4 days | Moderate |
This table shows how different steroids vary in onset speed and likelihood of causing flares due to their solubility and particulate nature.
The Role of Injection Technique in Post-Shot Pain Worsening
Even with the right medication choice, technique plays a critical role in patient outcomes. An experienced practitioner ensures precise placement inside the joint or bursa with minimal trauma.
If the needle punctures sensitive structures like nerves or blood vessels accidentally or if multiple attempts are needed due to difficult access, post-injection pain can intensify.
Ultrasound-guided injections have gained popularity because they improve accuracy by allowing real-time visualization of anatomical landmarks. Studies show ultrasound guidance reduces complications and improves patient comfort compared with blind injections.
Proper needle gauge selection also matters; smaller needles cause less tissue disruption but may be harder to maneuver into tight spaces. Balancing these factors takes skill honed through clinical practice.
Cortisone Shot Side Effects Beyond Temporary Pain Increase
While temporary worsening of pain is one known side effect, cortisone shots carry other risks worth noting:
- Tissue damage: Repeated injections can weaken tendons or cartilage over time.
- Steroid flare: Already discussed but important as it mimics infection symptoms without actual infection.
- Skin changes: Thinning or discoloration near injection site.
- Infection risk: Rare but serious if aseptic technique fails.
- Blood sugar spikes: Particularly relevant for diabetics.
- Nerve damage: Very uncommon but possible with poor technique.
These potential downsides underscore why doctors limit cortisone shots to 3-4 per year per joint or tissue area.
The Timeline: What To Expect After Your Cortisone Shot?
Understanding typical symptom progression helps manage expectations:
- The first 24-48 hours: Possible flare-up with increased pain/swelling due to crystal irritation.
- The first week: Gradual reduction in inflammation; some patients begin feeling relief.
- The next 1-3 weeks: Significant decrease in pain and improved function for many individuals.
- The long term (up to several months): Benefits may last from weeks up to several months depending on condition severity.
If worsening symptoms persist beyond 48 hours or worsen dramatically later on, contacting your healthcare provider is essential as this may indicate infection or other complications.
Treatment Options for Managing Post-Injection Pain Flares
If you experience increased discomfort after a cortisone shot, several strategies can help ease symptoms:
- Icing: Applying ice packs intermittently reduces swelling and numbs irritated nerve endings.
- Pain relievers: Over-the-counter NSAIDs like ibuprofen can help control inflammation without interfering significantly with steroid action.
- Avoid strenuous activity: Resting the affected joint or area prevents aggravation during healing phase.
- Mild compression: Using wraps or braces supports tissues without restricting blood flow excessively.
- If severe symptoms develop: Seek medical advice promptly for evaluation and possible antibiotic therapy if infection suspected.
These supportive measures usually suffice until steroid effects take hold fully.
The Science Behind Why Some People Don’t Respond Well To Cortisone Shots
Not everyone benefits equally from cortisone injections. Several reasons explain variable responses:
- Disease type & severity: Advanced arthritis with extensive cartilage loss responds less favorably than early-stage inflammation-driven conditions.
- Pain source complexity: If multiple overlapping problems exist—nerve entrapment plus joint inflammation—the shot might only address one aspect inadequately.
- Steroid resistance: Rare genetic variations affect how cells respond to corticosteroids at molecular levels.
- Psychological factors: Chronic pain syndromes sometimes involve central sensitization where peripheral anti-inflammatory treatments have limited impact.
Hence doctors often combine cortisone shots with physical therapy or other interventions tailored individually.
A Closer Look: Comparing Cortisone Shots With Other Pain Management Options
Cortisone injections are just one tool among many for managing musculoskeletal pain. Here’s how they stack up against alternatives:
| Treatment Type | Main Benefits | Main Drawbacks |
|---|---|---|
| Cortisone Shots | Rapid anti-inflammatory effect; localized treatment; few systemic side effects if done properly. | Pain flare risk; limited number per year; potential tissue weakening long term. |
| Nonspecific NSAIDs (oral) | Easily accessible; reduces systemic inflammation; effective for mild/moderate pain. | Poor targeting; gastrointestinal & cardiovascular risks with prolonged use; slower onset than injection. |
| Surgical Intervention (e.g., arthroscopy) | Treats structural issues directly; long-term solution for some conditions. | Surgical risks; recovery time; costly; not always necessary early on. |
| Physical Therapy & Exercise | No drug side effects; improves strength & flexibility; addresses root causes over time. | Takes longer for relief; requires patient commitment & consistency; |
Choosing among these depends on diagnosis specifics, severity, patient preferences, and prior treatment history.

Frequently Asked Questions
Can a cortisone shot make pain worse right after the injection?
Yes, a cortisone shot can cause a temporary increase in pain known as a “cortisone flare.” This happens when steroid crystals irritate the tissue at the injection site, usually lasting 24 to 48 hours before relief begins.
How common is it for a cortisone shot to make pain worse temporarily?
About 10-20% of patients experience increased pain shortly after receiving a cortisone shot. This temporary flare is a known reaction and typically resolves within a couple of days as inflammation decreases.
Why does a cortisone shot sometimes make pain worse before it gets better?
The steroid crystals in the injection can irritate tissues initially, causing inflammation and discomfort. This paradoxical reaction is short-lived, and once the irritation subsides, the anti-inflammatory effects provide significant pain relief.
Can the type of corticosteroid affect whether a cortisone shot makes pain worse?
Yes, some corticosteroid formulations are more likely to cause irritation and pain flares. The choice of corticosteroid and injection technique both influence how likely it is for pain to worsen temporarily after the shot.
What should I do if my pain gets worse after a cortisone shot?
If you experience increased pain following a cortisone injection, it’s usually best to rest and apply ice. The flare typically resolves within 1-2 days. Contact your doctor if pain persists or worsens beyond this period.
The Bottom Line – Can A Cortisone Shot Make Pain Worse?
Yes—a cortisone shot can make pain worse temporarily due to steroid crystal irritation causing a flare reaction immediately after injection. This effect generally lasts one to two days before subsiding as anti-inflammatory benefits kick in over subsequent weeks.
Proper injection technique combined with correct steroid selection minimizes risk of painful flares while maximizing therapeutic gains. Patients should anticipate possible short-term discomfort but remain confident that relief typically follows soon afterward.
For persistent worsening beyond expected timelines or signs of infection such as fever and redness around injection sites require urgent medical attention.
Ultimately, cortisone shots remain a valuable option for managing localized inflammatory pain despite occasional paradoxical flares making it seem like they worsen symptoms initially. Understanding this dynamic prepares patients emotionally while facilitating informed discussions with healthcare providers about best approaches tailored uniquely for them.
