TLDR
A cortisone injection reduces inflammation in a joint or tendon, but it does not correct the underlying cause of that inflammation. Relief often takes 5 to 7 days to develop and varies in duration. Without rehabilitation to address strength, load tolerance, and movement habits, pain frequently returns. At Ottawa Health: Performance and Rehab, cortisone injections for the hip, knee, and shoulder are available at $150 per injection, and our team supports patients through the recovery period with personalized physiotherapy.
Pain has a way of making the fastest-sounding solution feel like the right one. Whether you are training for a sport, managing a demanding work schedule, or trying to get through daily movement without discomfort, a cortisone injection can seem like an efficient and targeted answer. The logic feels straightforward: reduce the inflammation, reduce the pain, get back to life.
What surprises many patients is that the process rarely works quite that simply. The shot may take days to work, the relief may not last indefinitely, and what happens in the weeks after the injection often matters more than the injection itself.
This post covers what patients in Ottawa commonly ask about cortisone injections: how much they cost, how long they take to work, how long the relief lasts, and why rehabilitation is frequently the piece that determines whether the improvement holds.
Why a Cortisone Shot Feels Like the Obvious Answer
When pain has already interrupted your training, your sleep, your work, or your ability to move comfortably, the appeal of an injection is understandable. It sounds precise and efficient, and the idea of avoiding weeks of appointments before seeing any change is genuinely attractive.
Cortisone is a corticosteroid medication. When injected into or near an inflamed joint, bursa, or tendon, it works to suppress the local inflammatory response. For conditions where inflammation is a primary driver of pain, such as bursitis, tendinopathy, or joint irritation, this approach addresses the symptom directly.
The expectation gap appears here. Reducing inflammation is not the same as resolving the reason the inflammation developed in the first place. Overload patterns, muscle weakness around a joint, training errors, workstation posture, and movement habits all influence how tissue responds over time. Cortisone does not adjust those factors. Many patients ask what to expect after a cortisone injection specifically because the recovery plan was not discussed before the appointment, and they are left managing the response without clear guidance.
How Much Is a Cortisone Injection?
The cost of a cortisone injection varies depending on where you receive it, who administers it, whether imaging guidance is used, and what provincial or private insurance coverage applies to your situation.
At Ottawa Health: Performance and Rehab, cortisone injections for the hip, knee, and shoulder are offered at $150 per injection. Patients are encouraged to confirm their specific coverage and fee details before booking, whether they are going through a family physician, sports medicine physician, private clinic, or specialist referral pathway.
Cost is a reasonable starting point, but a more complete question is whether the injection fits your diagnosis, your goals, and your recovery plan. Before booking, it helps to clarify the following:
- What diagnosis is the injection treating, and is cortisone appropriate for it?
- Is imaging guidance recommended for the injection site?
- What costs are covered by your insurance, and what is out-of-pocket?
- What activity restrictions apply after the injection, and for how long?
- Should physiotherapy begin before or after the injection?
These questions help patients make informed decisions and avoid paying for a service that is not well-matched to their clinical picture. Our team at Ottawa Health: Performance and Rehab is available to discuss how an injection fits into a coordinated care plan.
How Long Does a Cortisone Shot Take to Work?
A cortisone injection does not produce immediate relief for most patients. If a local anesthetic is used alongside the steroid, some temporary numbness or reduction in pain intensity may occur quickly. The steroid component itself takes longer to act.
MedlinePlus notes that steroid injections generally take about 5 to 7 days to begin working. Mayo Clinic notes that a short-term flare of pain or swelling is possible in the first one to two days after the injection, before the anti-inflammatory effect develops.
A general timeline for what patients often experience looks like this:
Time Period | What to Expect |
First 24 to 48 hours | Possible soreness, stiffness, or a short-term flare at the injection site. Relative rest is generally recommended. |
Days 3 to 7 | Inflammation begins to settle for many patients. Pain and movement tolerance start to shift if the injection is effective. |
Weeks 1 to 3 | A clearer picture of pain relief and activity tolerance develops. Physiotherapy often begins or progresses during this period. |
Beyond 3 weeks | Rehabilitation progression and symptom response guide next steps, including return-to-activity planning. |
Individual responses vary based on the body region injected, the diagnosis, activity level, and medical history. These timeframes are general reference points, not fixed expectations.
How Long Does Pain Relief Last After a Cortisone Injection?
Relief duration ranges widely. Some patients notice improvement that holds for several weeks or months. Others experience shorter-lasting relief or find the injection does not produce meaningful change for their particular condition.
What patients are often surprised to learn is that pain relief fades when the original drivers of inflammation remain unaddressed. Overloading a joint repeatedly, training without adequate recovery, sitting in positions that compress an already-irritated structure, or returning to high-volume activity too quickly can all re-trigger the response that led to the injection in the first place.
For younger athletes and active adults between the ages of 15 and 30, reduced pain can create a false signal that tissue is ready for full-speed sport, heavy lifting, or high-load training. The inflammatory response may have settled, but structural tolerance and strength often need time to rebuild. Rushing this step is a common reason patients end up back where they started.
For sedentary professionals and older adults, reduced pain opens a realistic window to begin rebuilding mobility, strength, and functional movement with a measured approach. The goal is to use that window actively, not to wait and see whether the relief holds on its own.
Is Rehabilitation Needed After a Cortisone Shot?
For most patients, yes. Cortisone addresses the inflammatory response; it does not rebuild the strength, range of motion, or movement patterns that support a joint or tendon under load.
Physiopedia describes the post-injection period as a window of opportunity to begin appropriate rehabilitation while symptoms are reduced. That window is most useful when there is a clear plan for what to do with it.
Physiotherapy after a cortisone injection typically focuses on the following areas through our joint injection and rehabilitation services:
- Restoring range of motion without provoking symptoms
- Rebuilding strength in the muscles supporting the affected joint or tendon
- Improving load tolerance for sport, work tasks, stairs, and daily movement
- Adjusting training volume, recovery habits, workstation setup, or footwear where relevant
- Creating a staged return-to-activity plan with clear progression markers
Without this structure, a patient who feels better after an injection is still carrying the same movement deficits, load habits, and conditioning gaps that contributed to the problem. Asking whether rehabilitation is needed after a cortisone shot is a practical and worthwhile question, because the answer shapes how well the relief period is used.
What to Clarify Before and After the Injection
Staying informed and active throughout the process leads to better outcomes than passively waiting for the injection to resolve the problem.
Before the Injection
- Confirm the diagnosis and why cortisone is being recommended for your specific condition.
- Ask how long the injection is expected to take before any effect is noticeable.
- Ask which activities to pause and for how long after the injection.
- Ask whether physiotherapy should begin before or after the injection, and what the transition plan looks like.
After the Injection
- Track changes in pain, swelling, sleep quality, and activity tolerance over the first week.
- Avoid returning to maximal training or high-load activity because symptoms have settled. Symptom reduction is not the same as full tissue readiness.
- Book or continue physiotherapy to guide safe progression toward your movement goals.
- Contact your medical provider promptly if you notice fever, increasing redness, severe swelling, or pain that worsens rather than improves after the first 48 hours.
Key Takeaways
- Cortisone is a corticosteroid medication that reduces local inflammation when injected into a joint, bursa, or tendon. It does not repair tissue or correct the underlying cause of inflammation.
- According to MedlinePlus, cortisone injections typically take 5 to 7 days to begin working. A short-term flare of soreness in the first 24 to 48 hours is common and does not mean the injection has failed.
- Pain relief duration varies from person to person and depends significantly on whether the factors that caused inflammation are also being addressed.
- For most patients, rehabilitation is needed after a cortisone shot to rebuild strength, mobility, and load tolerance before returning to full activity.
- At Ottawa Health: Performance and Rehab, cortisone injections for the hip, knee, and shoulder are available at $150 per injection, with personalized physiotherapy support available to guide recovery.
- The most productive approach to a cortisone injection is to treat it as one part of a coordinated plan, not a standalone solution.

Frequently Asked Questions
How long does a cortisone shot take to work?
Most patients notice a change within 5 to 7 days, though individual responses vary. MedlinePlus notes this as a general timeframe for the steroid effect to develop. If a local anesthetic is included, some temporary relief at the injection site may occur more quickly, but this is separate from the anti-inflammatory response of the steroid itself.
What should I expect after a cortisone injection?
Mild soreness or a short-term flare at the injection site is common in the first 24 to 48 hours. Activity restrictions depend on the body region injected and the instructions from the administering provider. A physiotherapist guides the return to movement once you are cleared to begin progressing activity.
Is rehabilitation needed after a cortisone shot?
For most patients, yes. Cortisone addresses inflammation, but it does not rebuild the strength, range of motion, or movement tolerance that support a joint or tendon over time. Rehabilitation uses the reduced-pain period to address those factors in a structured way, which helps reduce the likelihood of the problem returning.
