Why Does Your Heel Hurt When You Take Your First Steps in the Morning?
Have you ever experienced a sharp pain under your heel when getting out of bed in the morning? Or noticed that walking becomes uncomfortable after sitting for a long time?
You might be experiencing a condition called plantar fasciitis.
It is one of the common causes of heel pain and can interfere with everyday activities, from walking and exercising to simply standing for extended periods.
While many people improve with conventional treatments, some continue experiencing pain despite physiotherapy, stretching exercises, footwear modifications and medication.
This raises an important question: Are there other treatment options worth exploring?
One option receiving considerable attention in medical research is Platelet-Rich Plasma (PRP) therapy.
What Is Plantar Fasciitis?
The plantar fascia is a thick band of connective tissue that runs along the bottom of your foot, connecting your heel bone to the toes.
It supports the arch of your foot and absorbs stress during walking, running and other physical activities.
Repeated strain or excessive loading can cause irritation and degenerative changes in this tissue, resulting in plantar fasciitis (often referred to clinically as plantar fasciopathy).
Common symptoms include:
- Sharp pain near the heel, particularly during the first few steps in the morning.
- Heel discomfort after prolonged sitting or resting.
- Pain that increases after extended walking or physical activity.
- Tenderness along the bottom of the foot.
- Difficulty standing or walking comfortably.
What Is PRP Therapy?
Platelet-Rich Plasma (PRP) therapy is a regenerative treatment that uses a concentrated portion of a patient’s own blood.
The process generally involves three steps:
- Blood collection: A small quantity of blood is collected from the patient.
- Centrifugation: The blood is processed to separate and concentrate platelets in the plasma.
- Targeted injection: The prepared PRP is injected into the affected area, often with ultrasound guidance.
Platelets contain growth factors and signalling proteins involved in the body’s natural repair processes.
The idea behind PRP therapy is to introduce a concentrated platelet preparation into the affected tissue to potentially support its healing response and improve symptoms.
How Can PRP Help in Plantar Fasciitis?
PRP is being investigated as an option for people experiencing persistent plantar fascia pain.
Researchers have explored its potential to:
- Support local tissue-repair processes.
- Improve pain and tenderness.
- Improve foot function and mobility.
- Provide longer-lasting symptom improvement in some patients.
Importantly, PRP is not an instant pain-relief treatment. Its potential benefits are generally evaluated over weeks and months, rather than immediately after injection.
What Does Published Medical Research Say About PRP for Plantar Fasciitis?
The effectiveness of PRP is not based solely on theoretical benefits. Several randomized controlled trials and systematic reviews have investigated its clinical outcomes.
Here are some notable findings.
1. A 2024 Systematic Review and Meta-Analysis: 1,356 Patients Studied
A systematic review published in Foot and Ankle Surgery in June 2024 analysed 21 randomized controlled trials involving 1,356 patients.
The researchers compared PRP with different treatment approaches, including:
- Corticosteroid injections.
- Extracorporeal shockwave therapy (ESWT).
- Placebo treatments.
- Other conservative treatment approaches.
What did they find?
PRP demonstrated statistically significant improvements in pain scores compared with corticosteroid injections, shockwave therapy and placebo.
It also showed better functional scores compared with corticosteroid injections and placebo.
However, PRP did not demonstrate superiority across every outcome measured. For example, improvements in foot function were not significantly different from several other treatment approaches.
This suggests that PRP may be a promising option, particularly for pain reduction, although results depend on the outcome being evaluated.

2. Randomized Clinical Trial: PRP Compared With Steroid Injections
A 2023 randomized clinical trial published in BMC Musculoskeletal Disorders studied 90 patients with plantar fasciitis who had not improved with conservative treatment.
Participants were divided into two groups:
- One group received PRP injections.
- The other received corticosteroid injections.
Researchers assessed pain, foot function and plantar fascia thickness over six months.
What were the results at six months?
| Measurement | PRP group | Steroid group |
|---|---|---|
| Pain score (VAS) | 1.97 | 2.71 |
| Foot function score (AOFAS) | 86.04 | 81.23 |
| Plantar fascia thickness | 3.53 mm | 4.58 mm |
The PRP group demonstrated better average outcomes across these measurements at the six-month assessment.
These results suggest that PRP may offer better medium-term improvement than corticosteroid injections in some patients.
However, the researchers also highlighted the need for larger studies and longer follow-up.

3. What Do Clinical Practice Recommendations Say?
A 2024 multispecialty consensus report on regenerative medicine and chronic pain also reviewed PRP evidence.
Its recommendations identified evidence supporting better long-term pain relief and physical function with PRP for plantar fasciitis compared with placebo and corticosteroid injections, particularly over six to 24 months.
This adds to the growing body of evidence supporting further consideration of PRP in appropriately selected patients.

PRP vs Steroid Injections: What Is the Difference?
Both treatments are used in the management of persistent plantar fasciitis, but they work differently.
| PRP therapy | Corticosteroid injection |
|---|---|
| Uses a preparation derived from the patient’s own blood. | Uses an anti-inflammatory medication. |
| Investigated for its potential to support tissue-repair processes. | Primarily used to reduce inflammation and pain. |
| Benefits may develop gradually. | May provide relatively rapid short-term pain relief. |
| Some studies show better medium- and long-term outcomes. | Benefits may diminish over time. |
Neither treatment is suitable for everyone. The choice depends on the diagnosis, severity, medical history and individual treatment goals.
Is PRP the Right Treatment for Everyone With Plantar Fasciitis?
Not necessarily.
Most people with plantar fasciitis initially benefit from conservative management, including:
- Appropriate footwear and supportive insoles.
- Calf and plantar fascia stretching exercises.
- Physiotherapy and progressive loading.
- Activity modification.
- Pain management where clinically appropriate.
PRP may be considered for selected patients who continue to experience symptoms despite appropriate conservative treatment.
A proper clinical assessment is important before deciding whether an injection-based treatment is appropriate.
What Should You Expect After PRP Treatment?
PRP is not designed to provide immediate pain relief.
Some patients may experience temporary soreness or discomfort following the injection. Improvement, if it occurs, is generally assessed over the following weeks and months.
A treating clinician may recommend a rehabilitation programme alongside the procedure.
The response varies between individuals, and no particular outcome can be guaranteed.
Frequently Asked Questions
1. Is PRP effective for plantar fasciitis?
Clinical studies and systematic reviews suggest that PRP can improve pain and certain functional outcomes in patients with chronic plantar fasciitis. However, results vary, and further research is needed to establish the best treatment protocols.
2. How long does PRP take to work for heel pain?
PRP is not an immediate pain-relief treatment. Its effectiveness is generally evaluated over several weeks and months, with some clinical trials reporting improvements at three- and six-month follow-ups.
3. Is PRP better than steroid injections for plantar fasciitis?
Several randomized trials and meta-analyses report better medium- or long-term pain outcomes with PRP. Steroid injections may offer faster short-term relief. Treatment decisions should be individualised.
4. Can plantar fasciitis be treated without surgery?
Yes. Most cases can be managed without surgery using stretching, physiotherapy, appropriate footwear and activity modification. Selected persistent cases may require additional interventions.
5. Is PRP made from your own blood?
Yes. Autologous PRP is prepared from a patient’s own blood, which is collected and processed to concentrate platelets.
