What is it? Plantar fasciitis is an extremely common, often debilitating condition that causes pain under the heel of the foot. It involves inflammation, irritation, or micro-tears in the plantar fascia, which is a thick, fibrous band of connective tissue that runs along the bottom of the foot, connecting the heel bone (calcaneus) to the toes. This tissue plays a crucial role in supporting the foot's arch and absorbing shock when we walk.

The condition typically results from repetitive strain or overload on the fascia. This strain can cause small tears in the tissue, leading to inflammation and, consequently, pain. It is most commonly seen in people between the ages of 40 and 60, but it can affect people of all ages, especially those who are physically active.

What are the symptoms? The hallmark symptom of plantar fasciitis is a sharp, stabbing pain on the bottom of the heel. This pain is characteristically most severe with the first few steps in the morning, after rising from a prolonged period of rest (like sitting for a long time), or when first starting to walk after a long car ride.

Patients often describe the pain as a searing or burning sensation that feels like a knife is being pushed into the heel. While the intensity of the pain usually subsides as the fascia warms up and stretches during activity, it can worsen throughout the day, particularly after long periods of standing or walking. The pain might also escalate immediately after intense exercise, rather than during it. Swelling and tenderness around the bottom of the heel are also common.

What are the causes and risk factors? Plantar fasciitis is seldom caused by a single event. It is typically the result of the cumulative effect of various factors that increase tension on the plantar fascia:

• Age: The tissue can naturally lose elasticity with age.
• Physical Activity: Engaging in high-impact activities like running, dancing, or long-distance walking can strain the fascia.
• Foot Mechanics: Having flat feet (overpronation) or high arches (supination), an abnormal walking pattern, or a tight Achilles tendon (the muscle that connects the calf muscles to the heel) can all contribute to excessive strain.
• Footwear: Wearing worn-out shoes or shoes with inadequate arch support and sole cushioning, or walking barefoot on hard surfaces, can exacerbate the problem.
• Weight: Being overweight can put extra stress on the feet.
• Occupation: Professions that require long hours of standing or walking on hard surfaces, such as nursing, teaching, or factory work, increase risk.

What are the treatment options? The vast majority of plantar fasciitis cases can be successfully resolved with non-surgical treatments. A private podiatrist will tailor a comprehensive treatment plan to your specific needs, which may include:

• Biomechanical Assessment and Gait Analysis: A detailed examination of your foot structure, movement, and walking pattern using advanced technology like pressure plates or slow-motion video. This helps identify any underlying mechanical issues contributing to the condition.
• Custom Orthotics: Bespoke insoles designed from a 3D scan of your feet. Unlike off-the-shelf inserts, custom orthotics provide precise arch support and cushioning, redistributing pressure away from the inflamed fascia.
• Specific Stretches and Strengthening Exercises: Targeted stretching routines for the calves, the Achilles tendon, and the plantar fascia itself are crucial for improving flexibility and reducing strain.
• Extracorporeal Shockwave Therapy (ESWT): A highly effective, non-invasive treatment that uses acoustic waves to stimulate healing in the inflamed tissue, particularly beneficial for chronic, stubborn cases.
• Night Splints: These devices hold the foot in a stretched position overnight, preventing the fascia from contracting and reducing morning pain.
• Supportive Footwear: Advice on choosing footwear with good arch support and ample cushioning for all daily activities.
• Manual Therapy and Massage: Hands-on techniques to release muscle tension and improve foot mobility.
• Taping/Strapping: Applying specialized tape can provide temporary support to the arch and fascia, reducing strain during activity.
