Plantar Fasciitis

Plantar fasciitis

Plantar fasciitis is probably the most common cause of pain under the heel. It is inflammation, or more likely degeneration of the thick band of tissue under your foot called the plantar fascia. Symptoms consist of pain under the heel, which often radiates into the arch. Pain is worse first thing in the morning, however, ease as your foot warms up. Treatment involves reducing pain and inflammation, correcting any biomechanical problems as well as stretching & strengthening exercises.

Symptoms of Plantar fasciitis usually develop gradually over time and include:

  • Pain under the heel.
  • Sometimes the pain radiates into the arch of your foot.
  • Tenderness under your heel when pressing in.
  • Pain is usually worse first thing in the morning.
  • Symptoms improve as your foot warms up, but return later.

Injuries with similar symptoms include:

What is Plantar fasciitis?

Plantar fasciitis is inflammation (or degeneration) of the Plantar fascia at the point it attaches to the heel.

The Plantar Fascia (or plantar aponeurosis) is a broad, thick band of tissue under the foot. It runs from under the heel bone (calcaneus), to the ball of the foot. It provides support to your foot when standing and shock absorption when running.

Plantar fasciitis or Plantar fasciopathy?

The term Plantar fasciitis describes inflammation (‘itis’ means inflammation). Traditionally people thought inflammation was the problem. However, studies now show inflammatory cells are not present in most cases.

Therefore, degeneration of the tissues is a more likely cause. In this case, the term Plantar fasciopathy is probably more accurate because it describes degeneration/wear and tear.

What causes Plantar fasciitis?

Overuse is the main cause of Plantar fasciits. However, there are a number of factors which increase your chances of developing it. These include poor foot biomechanics, for example, overpronation, or if you have a rigid, high-arched foot. Inappropriate footwear is another factor. For example, wearing very flat or unsupportive shoes. Or wearing the wrong running shoes for your foot type.

If you are heavy or overweight then this increases the load on your foot. Or if you have tight calf muscles or plantar fascia then you are also at a higher risk of injury.

Plantar fasciitis treatment

The following treatment methods form part of our full rehabilitation program. The aim of treatment is to protect your foot, and reduce pain and inflammation.

Cold therapy

Apply ice or cold therapy every couple of hours for 10 to 15 minutes in order to reduce pain and inflammation. Reduce this to 3 times a day as your symptoms improve.


Applying Plantar fasciitis taping often instantly relieves symptoms. It works by supporting the arch of the foot and as a result, reduces the strain on the plantar fascia. Therefore, allowing tissues to heal.

Footwear & Insoles

Wear comfortable shoes or supportive trainers and avoid hard or flat-soled shoes. Cushioning heel pads or insoles help relieve pain. However, if your overpronate (your foot rolls in or flattens) then orthotic-type insoles are more appropriate.

Plantar fasciitis night splint

The night splint or sock is worn overnight and helps prevent the fascia and calf muscles from tightening up.


Deep tissue massage to the arch of the foot helps stretch and relax the plantar fascia. Avoid the painful area near the heel, especially if it is acutely painful.


Your physiotherapist may use Extracorporeal shock wave therapy or Ultrasound therapy.


Your doctor may prescribe anti-inflammatory medication such as ibuprofen. This is effective in the early stages to reduce pain and inflammation. However, studies show long-term use may actually inhibit healing. Also, check with a doctor or pharmacist before taking medication.

Gait analysis

Gait analysis involves analysing your feet and how you walk and run. If you overpronate, or your feet flatten then orthotic inserts may be prescribed to correct biomechanical issues

Platelet-rich plasma injections

For more stubborn injuries a doctor may try a corticosteroid injection. Platelet-rich plasma injections have also been shown to be effective. If symptoms do not resolve then surgery is an option but this is rare.

Plantar fasciitis exercises

Exercises to stretch the plantar fascia and the calf muscles are particularly important. Rest alone reduces pain and inflammation, however, if fascia tension is a cause then your pain is likely to recur.

Our full Plantar fasciitis rehab program includes stretching, strengthening, activation, movement control and functional exercises.

  • Stretching for the plantar fascia and calf muscles including foot rolling.
  • Strengthening of the foot and plantar fascia as well as the posterior chain (legs and hips).
  • Activation exercises to keep the hip muscles firing and in good condition.
  • Movement control to maintain balance and proprioception.
  • Functional exercises to bridge the gap between basic rehab and sports-specific training.

Plantar fasciitis surgery

Surgery is indicated for around 5% of people, in particular, whose symptoms do not improve after a minimum of nine months of continuous treatment. However, the success rate is still only estimated at around 70-80%.

In most cases your surgeon perfoms a procedure called a plantar fascia release. This releases (cuts) between 30 and 50% of the fascia’s fibres. As a result, stress on the fascia reduces. However, possible complications include nerve damage, fallen arches, infection, and ongoing symptoms. Recovery after surgery, if successful is around 9 to12 weeks before the patient returns to work.
