What is plantar fasciitis?
Plantar fasciitis is the most common cause of heel pain in adults. The plantar fascia is a thick band of tissue running from the heel bone to the toes that supports the arch of the foot. With repeated overload, it develops small tears and degenerative changes where it attaches to the heel. Because inflammation is often limited, some doctors prefer the term plantar fasciopathy or plantar fasciosis.
Typical symptoms include:
- Sharp or stabbing pain under the heel, often on the inner side
- Pain that is worst with the first steps in the morning or after sitting
- Pain that eases with gentle walking but returns after long standing or activity
- Tenderness when pressing the bottom of the heel
The NHS plantar fasciitis page and the Mayo Clinic plantar fasciitis guide describe the condition in more detail.
Causes and risk factors
Plantar fasciitis results from load on the fascia exceeding its capacity to adapt. Risk factors include:
- Age between about 40 and 60
- Excess body weight
- Jobs that involve long periods of standing on hard surfaces
- Running, especially with sudden increases in distance
- Tight calf muscles or Achilles tendon, which limit ankle movement
- Flat feet, high arches or unsupportive footwear
Heel spurs are often seen on X-ray, but they are also common in people without heel pain and are not considered the main cause.
Diagnosis: when imaging helps
Plantar fasciitis is usually diagnosed from the history and examination. Ultrasound can confirm a thickened plantar fascia (often more than 4 mm) and guide injections. X-rays help rule out stress fractures and arthritis. MRI is useful when pain persists despite good treatment or when other causes are suspected, such as a calcaneal stress fracture, a fascia tear, fat pad atrophy or nerve entrapment (for example Baxterβs nerve or tarsal tunnel syndrome).
If you have had heel pain for six months or more and have imaging, you can send your MRI or ultrasound report for a doctor review to confirm the diagnosis before choosing treatment.
Conventional plantar fasciitis treatment
- Stretching and loading exercises. Plantar fascia-specific stretches and calf stretches, plus progressive strengthening such as high-load heel raises, are the basis of plantar fasciitis physical therapy.
- Footwear and insoles. Supportive, cushioned shoes and off-the-shelf or custom insoles reduce strain. Avoid walking barefoot on hard floors.
- Load management and weight loss. Temporarily reducing running or standing time, and losing weight if needed.
- Taping and night splints. Can help some people, particularly with morning pain.
- Pain relief. Ice and short courses of anti-inflammatories.
- Extracorporeal shockwave therapy (ESWT). An option for chronic plantar fasciitis; several trials and meta-analyses report pain reduction, although results vary between studies.
- Steroid injection. Gives short-term relief, but the effect often fades, and repeated injections carry a risk of fat pad atrophy and fascia rupture.
- Surgery (plantar fascia release). Reserved for persistent, disabling pain after 6 to 12 months of non-surgical care.
Regenerative options: what the evidence says
- PRP therapy: plantar fasciitis is one of the better-studied uses of platelet-rich plasma. Multiple randomised trials and meta-analyses have compared PRP with steroid injection and found similar early pain relief, with PRP often performing as well or better at six months and beyond. Study quality and PRP preparation vary. See PubMed trials of PRP versus corticosteroid for plantar fasciitis.
- Stem cell therapy: very limited evidence. Small studies of cell-based or placental tissue products exist, but there are no large controlled trials. See PubMed research on stem cells for plantar fasciitis.
- Exosome therapy: no meaningful human evidence for plantar fasciitis yet.
PRP injection is legal in most countries but is not a routine first-line treatment in public health systems. Stem cell products for this use are not approved in the US, UK or Australia; the US FDA warns about unapproved stem cell therapies.
Comparing plantar fasciitis treatment options
| Option | When used | Evidence | Typical effect | Main downside |
|---|---|---|---|---|
| Stretching and strengthening | First line | Moderate to strong | Builds over weeks | Needs daily routine |
| Insoles and footwear | First line | Moderate | Reduces strain | Comfort varies |
| Steroid injection | Severe pain | Moderate, short term | Fast, often fades | Fat pad atrophy, rupture risk |
| Shockwave therapy (ESWT) | Chronic cases | Moderate | Gradual over months | Several sessions; discomfort |
| PRP injection | Chronic cases | Moderate, growing | Often longer-lasting than steroid | Not standard everywhere |
| Stem cell injection | Experimental | Very limited | Uncertain | Unproven |
| Plantar fascia release | Persistent, disabling | Moderate | Variable | Surgical risks, arch changes |
Self-help for plantar fasciitis
- Stretch the calf and plantar fascia before your first steps in the morning
- Roll the arch over a cold bottle or a ball for a few minutes each day
- Wear supportive shoes indoors as well as outdoors
- Swap running for cycling or swimming while pain settles
- Increase activity gradually once pain improves
Who may be a candidate for regenerative treatment?
- Heel pain for more than three to six months despite stretching, footwear changes and physiotherapy
- A thickened plantar fascia confirmed on ultrasound or MRI
- People who prefer to avoid repeated steroid injections or surgery
- Realistic expectations; improvement usually develops over weeks to months
Who should not have regenerative treatment
- Heel pain from another cause, such as stress fracture, nerve entrapment or inflammatory arthritis
- Active foot infection or open wounds
- Bleeding or platelet disorders, active cancer or pregnancy
- Recent steroid injection into the same area (a waiting period usually applies)
Risks and side effects
Heel injections are often painful and can cause soreness for several days, sometimes more than a week. Rare risks include infection, bruising, nerve irritation and, mainly with steroid, fat pad thinning or fascia rupture. Cell-based treatments add harvest-site soreness if your own fat or marrow is used. Cells used in our programmes are prepared in ISO 9001:2015-certified partner laboratories.
What a plantar fasciitis treatment trip to Bangkok looks like
- Before travel: send your ultrasound, X-ray or MRI and reports on WhatsApp. A doctor reviews whether a regenerative program is reasonable.
- Day 1: consultation, foot examination and ultrasound assessment.
- Day 2: ultrasound-guided injection according to the protocol, sometimes combined with other therapies.
- Following days: review, footwear advice and a home exercise program.
Most heel programmes need around 3 to 5 days in Bangkok. Patients travel from Australia, the UK, the US and Canada. See how it works. No outcome can be guaranteed.
Recovery and aftercare at home
- Reduce walking and standing for the first few days; a walking boot is sometimes advised
- Avoid anti-inflammatory medicines for the period your doctor recommends after PRP
- Restart stretching, then gradually build strengthening exercises
- Return to running slowly over several weeks
- Update the medical team on WhatsApp and review progress after six to twelve weeks
Increasing redness, heat, swelling or fever after an injection needs urgent medical care.
Frequently asked questions
Can plantar fasciitis be cured?
Most people recover fully. Plantar fasciitis usually settles with stretching, footwear changes and load management, although it can take 6 to 12 months. A minority develop long-lasting heel pain that needs further treatment such as shockwave therapy or injections.
What is the fastest way to relieve plantar fasciitis pain?
Stretching the calf and the sole of the foot before getting out of bed, wearing cushioned supportive shoes, rolling the foot over a cold bottle, and reducing standing and running help most people. A steroid injection can relieve pain quickly but its effect often fades within weeks.
Is PRP effective for plantar fasciitis?
Several randomised trials and meta-analyses suggest PRP injections give similar or better pain relief than steroid injections, particularly at six months or longer, with fewer concerns about fascia rupture. Study quality varies, so PRP is usually offered after first-line care has failed.
Does stem cell therapy help plantar fasciitis?
Evidence is very limited. A few small studies have used cell-based or placental tissue injections for chronic plantar fasciitis, but there are no large controlled trials. Stem cell treatment should be considered experimental for this condition.
Do I need an MRI for plantar fasciitis?
Usually not. Diagnosis is mostly clinical, and ultrasound can show a thickened plantar fascia. MRI or X-ray is useful when pain persists despite treatment, to rule out stress fractures, nerve entrapment or other causes.
How much does plantar fasciitis treatment in Bangkok cost?
It depends on your diagnosis, imaging and the program a doctor recommends. Send your ultrasound, MRI or reports on WhatsApp for a free doctor review and a personalised program.
