Yes — PRP can be an effective option for chronic plantar fasciitis that has not responded to rest, stretching, orthotics, or physiotherapy.
A sharp, stabbing pain in the heel first thing in the morning is one of the most recognisable symptoms in orthopaedic medicine. It often returns after sitting for a while and then getting up. Plantar fasciitis is the leading cause of heel pain in adults. It affects around 10% of people at some point in their lives. For many, it resolves with time and conservative treatment. For others, it becomes a persistent, quality-of-life-limiting problem that can last for months or years.
This guide is for people with stubborn heel pain in Sydney’s north-west, the Hills District, or the Southern Highlands. It explains plantar fasciitis and why it is so common. It also covers the full range of treatment options, up to and including regenerative therapies like PRP.
What Is Plantar Fasciitis?
The plantar fascia is a thick band of connective tissue that runs along the sole of the foot. It connects the heel bone (calcaneus) to the base of the toes. It acts as a shock absorber and supports the arch of the foot. During walking, running, and standing, it bears significant tensile load.
Plantar fasciitis was historically thought to be an inflammatory condition, hence the “-itis” suffix. More recent research has shown it to be a degenerative process, sometimes called plantar fasciosis. In this process, the collagen fibres of the fascia at the heel attachment become disorganised and undergo micro-tearing that fails to heal properly. This explains why anti-inflammatory treatments alone are often insufficient for chronic cases.
Symptoms
- Heel pain on the first steps in the morning — the hallmark symptom; pain is typically worst after rest and eases as you walk about
- Pain after prolonged standing or walking
- Tenderness at the front of the heel bone on the sole of the foot
- Tightness in the calf and Achilles tendon (often associated)
- In chronic cases, pain may become more constant
Who Is at Risk?
Several factors raise the risk of plantar fasciitis. These include being overweight, standing for long periods at work (nurses, teachers, retail workers), and recently increasing exercise load. Unsupportive footwear, tight calf muscles, and a high or low foot arch also contribute. It is also common in runners — particularly those who have recently changed their training volume or surface.
Conventional Treatment Options
The good news is that the majority of plantar fasciitis cases do resolve — but this can take 6–18 months. Proven first-line treatments include:
- Stretching — calf stretching and plantar fascia-specific stretching reduce tension at the heel attachment and are one of the most effective self-management strategies
- Footwear and orthotics — supportive footwear and custom or prefabricated insoles can significantly reduce symptoms by redistributing load away from the heel
- Physiotherapy — including manual therapy, taping, and progressive loading exercises
- Night splints — keep the foot in a dorsiflexed position overnight to gently stretch the fascia and reduce morning pain
- NSAIDs — for short-term symptom relief
- Cortisone injection — can provide rapid short-term relief for acute pain, but carries a risk of plantar fascia rupture with repeated injections and does not address the underlying degeneration
- Shockwave therapy (ESWT) — strong evidence for chronic plantar fasciitis that has not responded to conservative care; a common next step before more invasive options
When Conservative Treatment Is Not Enough
Some patients have chronic plantar fasciitis lasting more than 6 months. When conservative measures have been exhausted without lasting relief, the options narrow. Surgery (partial plantar fasciotomy) carries risks including arch collapse and nerve damage, and should be a last resort. This has driven significant interest in regenerative treatments, particularly PRP, as a bridge between conservative care and surgery.
PRP for Plantar Fasciitis
PRP therapy involves injecting a concentrated preparation of your own platelets and growth factors into the degenerated plantar fascia at the heel. Ultrasound guidance is used for precise placement. The growth factors stimulate the repair of the disorganised collagen tissue and promote the formation of healthy new connective tissue. They also address the biological deficit that is preventing natural healing.
The clinical evidence for PRP in plantar fasciitis is among the strongest of any tendon condition. Multiple randomised controlled trials have shown that PRP injection produces superior outcomes to cortisone at medium to long-term follow-up (3–12 months). Patients report greater reduction in pain, improved function, and higher rates of successful return to normal activities. The effect of PRP develops gradually — unlike the rapid but short-lived relief from cortisone — but the results are more lasting.
Seek Expert Assessment in Sydney’s North-West or the Southern Highlands
Not all heel pain is plantar fasciitis. Other causes such as heel fat pad atrophy, stress fracture, tarsal tunnel syndrome, and nerve entrapment also need to be considered. A thorough clinical assessment and appropriate imaging are important to confirm the diagnosis before proceeding with any treatment.
Dr John PRP provides thorough assessment and PRP treatment for heel and foot pain, with patients attending from Castle Hill, Norwest, Kellyville, Baulkham Hills, Pennant Hills, Bowral, Mittagong, and across the Southern Highlands.
If heel pain has been slowing you down, book a consultation today and find out whether PRP is an appropriate option for you.

Frequently Asked Questions
Can PRP treat plantar fasciitis?
Yes. PRP can be an effective option for chronic plantar fasciitis that has not responded to rest, stretching, orthotics, or physiotherapy. It uses concentrated platelets from your own blood to support healing at the plantar fascia.
How long does it take to recover from plantar fasciitis?
Chronic plantar fasciitis often improves gradually over several weeks to a few months. Combining treatment with appropriate footwear, stretching, and load management gives the best chance of a durable result.
How many PRP injections are needed for plantar fasciitis?
Many patients respond to one or two PRP injections, though this depends on the severity and how long the condition has been present. Your treatment plan is tailored following assessment.
Do I need a referral to be assessed for plantar fasciitis?
Not usually. If you already have a diagnosis you can often book directly. For more complex cases we may recommend consulting your GP first. We see patients across Sydney’s North-West and the Southern Highlands.
