Cortisone vs PRP Injections: Which Is Better?
Cortisone and platelet-rich plasma (PRP) injections work in different ways. The better option depends on the condition being treated, your goals, the expected benefits and risks, and the rehabilitation plan around the injection.

Assessment helps determine whether an injection may support a broader rehabilitation plan.
Are cortisone and PRP injections the same?
No. Cortisone and PRP are different treatments rather than interchangeable injections.
Cortisone is a corticosteroid medicine used to reduce inflammation and pain. PRP uses a concentrated sample of your own platelets and is intended to influence the local healing response. Which approach makes sense depends on the tissue involved, the diagnosis and what you are trying to achieve.
Cortisone injections
Cortisone may provide relatively fast pain relief when inflammation or irritation is contributing to symptoms. Benefits are often strongest in the short term.
PRP injections
PRP is usually considered when the aim is to influence a longer-term tissue response. Evidence varies substantially between different tendon and joint conditions.
If you are weighing up an injection, it also helps to consider broader pain management options and why your symptoms developed in the first place.
What do cortisone injections do?
A cortisone injection usually contains a corticosteroid medicine, sometimes combined with local anaesthetic. It may be considered when pain or inflammation is limiting movement, sleep or rehabilitation.
Examples include selected cases of shoulder bursitis, joint irritation and some rotator cuff-related shoulder presentations.
Some people notice symptom relief within days. However, cortisone does not automatically correct the reason a tendon, joint or other structure became painful.
Potential benefits of cortisone
- May provide relatively quick short-term pain relief.
- May help when pain is preventing rehabilitation from progressing.
- Can be useful for selected inflammatory or joint-related presentations.
- Is widely available through appropriate medical providers.
What are the limitations?
- Relief may be temporary.
- It does not repair damaged tendon fibres.
- Repeated corticosteroid injections may carry additional tissue risks in some situations.
- The benefit depends on the diagnosis, injection site and individual health factors.

When is PRP considered?
PRP stands for platelet-rich plasma. A clinician takes a sample of your blood and processes it to create a preparation with a higher concentration of platelets. This is then injected into the target area.
PRP may be discussed for selected longer-standing tendon or joint problems. Examples can include some cases of Achilles tendinopathy and other persistent tendon presentations.
The evidence is not the same for every condition. Results can vary with the tissue being treated, PRP preparation, injection technique, number of injections and rehabilitation program.
Potential benefits of PRP
- Uses material prepared from your own blood.
- May improve symptoms or function in selected tendon or joint conditions.
- May be considered when symptoms remain despite appropriate conservative care.
- Can form part of a structured rehabilitation plan.
What are the limitations?
- Research findings are mixed and condition-specific.
- Improvement, when it occurs, is not usually immediate.
- More than one treatment may sometimes be recommended.
- PRP can be more expensive and less accessible than cortisone.
- Soreness, bruising or bleeding can occur after blood collection or injection.
Is PRP better than cortisone?
There is no single answer for every injury. In rotator cuff tendinopathy research, corticosteroid injections tend to perform better for short-term pain relief. Some studies suggest PRP may produce more sustained improvement later, but findings remain inconsistent.
The decision should therefore be based on the specific diagnosis rather than simply choosing the injection with the strongest marketing claim.
Speed
Cortisone may act faster when short-term pain reduction is the main goal.
Evidence
Evidence for both injections varies according to the condition and tissue being treated.
Rehabilitation
Neither option removes the need to address strength, movement, workload and return to activity where these factors matter.
What about nerve blocks and Botox?
Cortisone and PRP are not the only injections used in pain and musculoskeletal medicine. Other injections have different purposes and should not be treated as direct alternatives to PRP or cortisone.
What are nerve blocks used for?
A nerve block places medication near a nerve or group of nerves to reduce pain signals. Clinicians may use nerve blocks for pain control around surgery, to help identify a likely pain source or to provide targeted pain relief in selected cases.
They are most useful when the clinical question and target nerve are clear. More widespread or persistent pain may need a broader assessment of pain types and causes.
Can Botox help pain or muscle overactivity?
Botulinum toxin, commonly known by the brand name Botox, also has medical uses. It has an established role in chronic migraine prevention and may be used for selected conditions involving muscle overactivity or spasticity.
People with temporomandibular disorder or some jaw-related pain presentations may also ask about Botox. Suitability depends on the diagnosis because reducing muscle activity can also temporarily reduce normal muscle strength.
What are the main risks of injection therapy?
All injections carry some risk. The type and likelihood of complications depend on the medication or biological product, injection site, technique and your health history.
- Temporary pain or soreness after the injection.
- Bruising or bleeding.
- Infection, although this is uncommon with appropriate sterile technique.
- Temporary numbness or weakness with some injections.
- Changes in blood glucose after corticosteroid injections, particularly for people with diabetes.
- Tissue-specific risks associated with repeated corticosteroid exposure.
Why does rehabilitation still matter after an injection?
An injection may reduce pain or change symptoms, but that does not necessarily restore strength, mobility or load tolerance.
This matters in problems such as tendinopathy, where progressive loading and movement planning are often central to longer-term management.
Depending on the condition, physiotherapy after an injection may include:
- graded strengthening
- mobility exercises
- load and activity modification
- movement or technique changes
- progressive return to work, gym or sport
- monitoring how symptoms respond as activity increases
The timing of exercise after an injection should match the injection type, tissue involved and advice from the clinician who performed the procedure.
What should you do before choosing an injection?
-
Clarify the diagnosis
Ask what structure or condition is believed to be causing your symptoms and how confident the diagnosis is.
-
Understand the goal
Find out whether the injection is intended to reduce pain, help confirm a diagnosis or support another part of treatment.
-
Discuss benefits and risks
Ask what improvement is realistically expected, how long it may last and which complications matter in your situation.
-
Plan what happens afterwards
Know when you can restart normal activity and whether physiotherapy, exercise or another treatment should follow.
What to do next
If you are considering cortisone, PRP or another injection, make sure the diagnosis and purpose of the procedure are clear first.
A physiotherapist can assess movement, strength, load tolerance and other factors that may be contributing to your symptoms. They can also help you decide whether rehabilitation should come first or help plan your recovery around an injection recommended by your doctor.

Cortisone and PRP injection FAQs
Do cortisone injections fix the cause of pain?
Not usually. Cortisone may reduce pain and inflammation, but it does not automatically correct factors such as weakness, stiffness, excessive load or reduced movement capacity. Rehabilitation may still be needed.
Is PRP better than cortisone?
It depends on the condition and treatment goal. Cortisone may provide faster short-term pain relief, while PRP is sometimes considered for selected longer-standing tendon or joint problems. PRP evidence remains mixed and condition-specific.
How quickly do cortisone and PRP injections work?
Cortisone may begin reducing symptoms within several days, although responses vary. PRP generally does not provide the same immediate anti-inflammatory effect and any improvement may develop more gradually.
What are nerve blocks mainly used for?
Nerve blocks may be used for post-surgical pain control, diagnostic clarification or targeted pain relief. Their usefulness depends on having an appropriate clinical reason and a clearly identified target.
Can Botox help migraines or jaw pain?
Botulinum toxin has an established medical role in chronic migraine prevention. It may also be considered in selected conditions involving muscle overactivity, including some jaw presentations, but suitability depends on the diagnosis and potential effects on normal muscle function.
Are injections enough on their own?
Often not. An injection may help control symptoms, but many musculoskeletal problems also require strength, mobility, load management or a graded return to normal activity.
