Plantar Fasciitis

What is Plantar Fasciitis?

Plantar fasciitis is a common condition that involves 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. This condition often causes stabbing pain that usually occurs with your first steps in the morning. The pain typically decreases as you move, but it might return after long periods of standing or getting up from sitting.


Common Names for Plantar Fasciitis

Plantar fasciitis is often referred to by several common names, which include:

  • Heel spur syndrome
  • Jogger’s heel
  • Tennis heel
  • Policeman's heel
  • Runner’s heel


Impact of Plantar Fasciitis on Anatomy and Health

When the plantar fascia becomes inflamed or irritated, it can lead to significant pain and discomfort. Here’s how it impacts your anatomy and health:

  • Pain and Inflammation: The primary symptom of plantar fasciitis is pain on the bottom of the heel. This pain can be sharp or stabbing, and it's often most severe in the morning or after long rest periods. The pain occurs because the plantar fascia is trying to heal and repair itself, but repeated stress and strain prevent it from doing so.
  • Biomechanical Changes: You might unconsciously change how you walk to avoid pain. These changes in gait can lead to other problems, such as pain in your knees, hips, and back, as your body tries to compensate for the altered movement.
  • Reduced Mobility: Persistent pain can limit your ability to perform daily activities. Simple tasks like walking, running, or standing for long periods can become challenging, affecting your overall quality of life.
  • Potential for Chronic Pain: If left untreated, plantar fasciitis can become a chronic condition. This prolonged pain can lead to other complications, including the development of heel spurs—bony growths on the bottom of the heel bone.
  • Impact on Physical Activity: Plantar fasciitis can significantly impact athletes' and active individuals' performance and participation in sports. The pain can limit your ability to train and compete, leading to decreased physical fitness and potentially contributing to other injuries due to altered mechanics.


Causes and Risk Factors for Plantar Fasciitis

Several factors can increase the risk of developing plantar fasciitis. These include:

  • Age: Plantar fasciitis is most common in people between 40 and 60, though it can occur at any age.
  • Occupational Risks: Jobs that require long periods of standing or walking on hard surfaces, such as teaching, factory work, or retail, can increase the risk. The constant pressure and strain on the feet can lead to plantar fascia inflammation.
  • Physical Activity: Athletes, particularly runners, are at a higher risk due to the repetitive impact on the feet. Activities that stress the heel and attached tissue, such as ballet, aerobics, and other high-impact sports, can also contribute.
  • Foot Mechanics: Certain foot structures, such as flat feet, high arches, or an abnormal pattern of walking, can affect the way weight is distributed when standing and put added stress on the plantar fascia.
  • Obesity: Excess weight can stress the plantar fascia more, increasing the risk of inflammation and pain. This is particularly significant because the plantar fascia supports the foot arch and absorbs the shock of walking.
  • Improper Footwear: Wearing shoes that don’t provide adequate support, particularly those with thin soles, poor arch support, or no cushioning, can increase the risk. High heels can also contribute to the condition by putting additional strain on the heel.
  • Sudden Weight Gain: Rapid weight gain, such as during pregnancy, can increase stress on the plantar fascia and lead to inflammation and pain.


Symptoms of Plantar Fasciitis

The primary symptom of plantar fasciitis is pain at the bottom of the heel. The pain can be sharp, stabbing, or dull and usually exhibits the following characteristics:

  • Morning Pain: Pain is often worse with the first few steps in the morning or after a period of rest. The stiffness and pain can decrease after a few minutes of walking but might return after prolonged periods of standing or after getting up from sitting.
  • Pain After Activity: Pain typically increases after exercise or activity, not during it. This is because the plantar fascia becomes more inflamed and irritated with use.
  • Localised Pain: Pain is usually felt in the bottom of the heel, but it can also extend into the foot's arch.
  • Tenderness: The bottom of the heel may be tender to touch, and pressing on the area can exacerbate the pain.


Preventing Plantar Fasciitis

Preventing plantar fasciitis involves minimising risk factors and adopting healthy habits to protect your feet. Here are some preventive measures:

  • Wear Proper Footwear: Choose shoes with good arch support, cushioning, and a proper fit. Avoid wearing high heels or shoes with thin soles for prolonged periods.
  • Maintain a Healthy Weight: Keeping your weight within a healthy range reduces the stress on your feet.
  • Stretch Regularly: Perform stretching exercises for the plantar fascia, Achilles tendon, and calf muscles to maintain flexibility and reduce tension in the foot.
  • Warm Up Before Exercise: Always warm up before engaging in physical activities to prepare your muscles and tendons for the stress of exercise.
  • Gradually Increase Activity Levels: When starting a new exercise routine, gradually increase the intensity and duration to avoid overloading your feet.
  • Use Proper Techniques: Ensure you use the correct techniques for running, jumping, and other physical activities. Consider working with a coach or trainer to improve your form.
  • Rest and Recovery: Allow time for rest and recovery, especially after intense physical activities, to prevent overuse injuries.
  • Avoid Prolonged Standing: If your job requires prolonged standing, take breaks to sit down and rest your feet. Consider using anti-fatigue mats if you need to stand for long periods.


Types of Plantar Fasciitis

Plantar fasciitis can be classified into the following categories for practical purposes:

  • Acute Plantar Fasciitis: This is a short-term condition often resulting from a specific injury or sudden increase in activity. It is characterised by sharp, intense pain that can be managed with rest, ice, and anti-inflammatory medications.
  • Chronic Plantar Fasciitis: When the condition persists for several months or even years, it is considered chronic. Chronic plantar fasciitis can result from ongoing overuse, inadequate treatment, or biomechanical issues. Treatment may require more intensive interventions, such as physical therapy, orthotics, or surgery.
  • Recurrent Plantar Fasciitis: This type occurs when symptoms resolve but return periodically, often due to repetitive stress or failure to address underlying causes. Prevention strategies and consistent use of supportive footwear are crucial for managing recurrent cases.
  • Mechanical Plantar Fasciitis: Caused by structural issues in the foot, such as flat feet or high arches, mechanical plantar fasciitis requires treatments that address these underlying problems, such as custom orthotics or footwear modifications.
  • Inflammatory Plantar Fasciitis: Associated with systemic inflammatory conditions like rheumatoid arthritis, this type of plantar fasciitis requires managing the underlying inflammatory disease along with typical plantar fasciitis treatments.


Stages of Plantar Fasciitis

Plantar fasciitis typically progresses through several stages, reflecting the condition's severity and chronicity. Recognising these stages can help understand the progression and determine the appropriate treatment.

  • Early Stage (Acute Phase):
  • Symptoms: Sharp, stabbing pain in the heel, especially with the first steps in the morning or after rest periods.
  • Duration: This stage can last a few weeks to a few months.
  • Characteristics: Pain is usually intense but may improve with initial activity, only to worsen after prolonged standing or physical activity.
  • Subacute Stage:
  • Symptoms: Continued heel pain that persists throughout the day, though it might fluctuate in intensity.
  • Duration: This stage may last several months.
  • Characteristics: Pain becomes more consistent, and rest or typical over-the-counter treatments may not provide significant relief.
  • Chronic Stage:
  • Symptoms: Persistent, chronic heel pain lasting several months or even years.
  • Duration: Pain persists for over six months.
  • Characteristics: The pain may become debilitating, affecting daily activities and leading to compensatory changes in gait, which can cause secondary issues in the knees, hips, and back.


Diagnosis of Plantar Fasciitis

  • Medical History:
  • The doctor will ask about your symptoms, including the nature, duration, and onset of pain. Information about your physical activities, job, footwear, and any recent changes in your routine is also gathered.
  • Physical Examination:
  • The doctor will examine your foot, focusing on areas of tenderness, particularly around the heel and arch. They might ask you to walk or perform certain movements to assess how your pain affects your gait.
  • Imaging Studies:
  • X-rays: Although plantar fasciitis doesn’t show up on X-rays, they can rule out other causes of heel pain, such as fractures or arthritis.
  • Ultrasound: This can be used to visualise the thickening and inflammation of the plantar fascia.
  • MRI: In rare cases, an MRI might be ordered to provide a detailed image of the soft tissues and rule out other conditions.


Treatment of Plantar Fasciitis

Treatment for plantar fasciitis typically begins with conservative measures. More invasive treatments are considered if these are ineffective. Common treatment options include:

  • Conservative Treatments:
  • Rest and Activity Modification: Reducing or avoiding activities aggravating the condition can help alleviate pain.
  • Ice Therapy: Applying ice to the affected area for 15-20 minutes several times daily can reduce inflammation and pain.
  • Stretching and Strengthening Exercises: Exercises that stretch the plantar fascia, Achilles tendon, and calf muscles can help relieve symptoms. Strengthening exercises for the foot and ankle can also be beneficial.
  • Orthotics and Footwear: Custom orthotics or insoles can provide additional support and reduce strain on the plantar fascia. It is crucial to wear shoes with good arch support and cushioning.
  • Medications: Over-the-counter pain relievers like ibuprofen or naproxen can reduce inflammation and pain.
  • Physical Therapy:
  • A physical therapist can design a treatment program that includes manual therapy, stretching, strengthening exercises, and modalities like ultrasound or shockwave therapy.
  • Advanced Treatments:
  • Corticosteroid Injections: In some cases, corticosteroid injections can reduce severe inflammation and pain.
  • Extracorporeal Shock Wave Therapy (ESWT): This non-invasive treatment uses shock waves to stimulate healing in the plantar fascia.
  • Platelet-Rich Plasma (PRP) Therapy: PRP involves injecting a concentration of your platelets into the affected area to promote healing.
  • Surgical Treatment:
  • Surgery is considered a last resort when conservative treatments fail. Procedures may involve releasing part of the plantar fascia to reduce tension and inflammation.


What if Plantar Fasciitis is Untreated?

If plantar fasciitis is left untreated, it can lead to several complications and chronic issues, including:

  • Chronic Pain: Persistent heel pain can become chronic, significantly affecting daily activities and overall quality of life. Chronic pain may lead to other issues, such as anxiety and depression.
  • Compensatory Injuries: To avoid pain, you might alter the way you walk, which can lead to compensatory injuries in other parts of the body, such as the knees, hips, and lower back.
  • Heel Spurs: Untreated plantar fasciitis can lead to the development of heel spurs—bony growths that form on the heel bone. While heel spurs are not always painful, they can contribute to ongoing discomfort and inflammation.
  • Reduced Mobility: Chronic pain and compensatory changes in gait can limit mobility, making it difficult to perform daily activities or participate in physical activities.
  • Decreased Quality of Life: Ongoing pain and functional limitations can impact overall well-being, reducing quality of life.


Recognising and addressing plantar fasciitis early is crucial for preventing these complications. If you experience persistent heel pain, it’s essential to consult a healthcare professional for a proper diagnosis and effective treatment plan. Early intervention can help alleviate pain, improve foot function, and prevent chronic issues.
