Causes & Symptoms of Plantar Fasciitis

By James Kirkpatrick

Plantar Fasciitis is an inflammation of the plantar fascia, a thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes. It’s a leading cause of heel pain and can significantly impact one’s quality of life.

Common Symptoms

Identifying the symptoms of plantar fasciitis is crucial for early intervention and effective treatment. While symptoms may vary from person to person, common indicators include:

Heel Pain

The hallmark symptom of plantar fasciitis is sharp, stabbing pain in the heel, typically occurring with the first steps in the morning or after prolonged periods of rest.

In advanced cases, the formation of heel spurs, bony protrusions on the underside of the heel bone, may contribute to persistent pain and inflammation.

 Overpronation, the excessive inward rolling of the foot during walking or running, can result in increased tension and strain on the plantar fascia. This abnormal foot mechanics disrupts the natural shock absorption and weight distribution mechanisms, leading to inflammation of the plantar fascia.

Abnormal foot arches, such as flat feet (pes planus) or high arches (pes cavus), can alter the distribution of weight and pressure on the foot. Flat feet may lead to overstretching of the plantar fascia, while high arches may result in excessive tension on the fascia, both of which can contribute to plantar fasciitis.

 Tightness in the calf muscles, particularly the gastrocnemius and soleus muscles, can restrict ankle mobility and affect the flexibility of the Achilles tendon. This reduced ankle dorsiflexion range of motion increases the load on the plantar fascia during activities such as walking or running, predisposing it to injury and inflammation.

A difference in leg length, whether anatomical or functional, can result in altered biomechanics and gait patterns. This imbalance can lead to asymmetrical loading of the lower extremities, potentially causing overuse injuries like plantar fasciitis on the longer limb due to compensatory mechanisms.

 Wearing shoes with inadequate arch support, cushioning, or stability can exacerbate biomechanical issues and increase the risk of plantar fasciitis. Improper footwear fails to provide adequate shock absorption and may contribute to abnormal foot pronation or excessive pressure on the plantar fascia.

 Inflammation of the plantar fascia may result in swelling or tenderness in the affected area.

Plantar fasciitis can affect your ability to walk or stand for extended periods, leading to stiffness, limping, or altered gait patterns.

Some experience pain or discomfort along the arch of the foot, particularly during weight-bearing activities.

Characteristics of Plantar Fasciitis

Pain Characteristics: The pain is usually described as a sharp, stabbing sensation in the heel, particularly severe with the first steps in the morning or after a period of rest.

Physical Signs: Swelling, redness, or feelings of warmth in the heel area may also be present.

Assessment: Recognising the characteristic pain and when it occurs can help identify Plantar Fasciitis

Causes of Plantar Fasciitis

Overuse: Repetitive stress and activities that place a lot of pressure on the foot, like running or standing for long periods, can lead to Plantar Fasciitis.

Obesity: Carrying extra weight puts additional stress on the plantar fascia, increasing the risk of inflammation.

Footwear: Wearing shoes that lack proper support or cushioning can contribute to the development of Plantar Fasciitis.

Age: The condition is more common in people between the ages of 40 and 60, as the plantar fascia loses elasticity with age.

Anatomy: Individuals with flat feet, high arches, or abnormal walking patterns are at a higher risk of experiencing Plantar Fasciitis. 

Treating Plantar Fasciitis

Treatments may include physical therapy, orthotic devices, anti-inflammatory medications, or in severe cases, surgery. Rest, ice, compression, elevation (RICE), stretching exercises, and wearing supportive shoes can alleviate symptoms.

Preventing Plantar Fasciitis

Lifestyle Modifications: Maintaining a healthy weight, choosing supportive footwear, and incorporating foot exercises into your routine can help prevent Plantar Fasciitis.


Understanding the causes and symptoms of Plantar Fasciitis is the first step toward effective management and treatment. Whether through professional medical advice or at-home care, individuals can find relief from the pain and discomfort associated with this condition.
