That sharp, stabbing pain in your heel first thing in the morning — or after sitting down for a while and then getting up — is one of the most recognisable symptoms in orthopaedic medicine. Plantar fasciitis is the leading cause of heel pain in adults, affecting 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.
If you’re dealing with stubborn heel pain in Sydney’s north-west, the Hills District, or the Southern Highlands, this guide explains the condition, why it is so common, and what the full range of treatment options includes — 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 your foot, connecting the heel bone (calcaneus) to the base of your 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), but more recent research has shown it to be a degenerative process — plantar fasciosis — in which 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?
Plantar fasciitis is more common in people who are overweight, who stand for long periods at work (nurses, teachers, retail workers), who have recently increased their exercise load, who wear unsupportive footwear, or who have tight calf muscles or a high or low foot arch. 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
For patients with chronic plantar fasciitis lasting more than 6 months, who have exhausted conservative measures without achieving 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 area of the plantar fascia at the heel, using ultrasound guidance for precise placement. The growth factors stimulate the repair of the disorganised collagen tissue, promote the formation of healthy new connective tissue, and 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 demonstrated that PRP injection produces superior outcomes to cortisone at medium to long-term follow-up (3–12 months), with patients reporting 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 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.
