The Foundation of Movement: Navigating Foot Pain from Plantar Fasciitis to Neuromas
The human foot, a marvel of engineering comprising 26 bones, 33 joints, and over 100 muscles, tendons, and ligaments, is the foundation of all upright movement. Yet, it is often the most neglected part of the body until pain forces us to pay attention. At Exercise Thought, nestled in the Dandenong Ranges, we understand that addressing foot pain isn't just about treating a symptom; it's about restoring the entire kinetic chain and enhancing quality of life.
In this insightful discussion, Principal Physiotherapist Sam Suke dives deep into the complexities of foot pain, offering a comprehensive guide for both patients seeking relief and clinicians refining their diagnostic skills.
1. The Common Culprits: Plantar Fasciitis, Achilles Tendinopathy, and Neuromas
The video highlights three prevalent causes of foot pain:
a) Plantar Fasciitis: The Morning Agony
What it is: Inflammation and degeneration of the plantar fascia, a thick band of tissue running along the bottom of your foot, connecting your heel bone to your toes.
Key Symptom: Classic "first-step pain" in the morning or after periods of rest, which often eases with activity but may worsen again later in the day.
Pathophysiology: Contrary to its name, plantar fasciitis is often less about acute inflammation ("-itis") and more about fasciosis—a degenerative process involving microscopic tears and disorganized collagen fibers. This means simple anti-inflammatories may offer limited long-term relief.
Risk Factors: High arches, flat feet, prolonged standing, obesity, sudden increases in activity, and inappropriate footwear are common contributors.
Exercise Thought's Approach: We emphasize a multi-pronged approach:
Load Management: Reducing aggravating activities while promoting active recovery.
Strength Training: Targeting intrinsic foot muscles and calf muscles (gastrocnemius and soleus), as weakness here increases strain on the fascia.
Stretching: Gentle calf and plantar fascia stretches.
Night Splints: To keep the foot in a dorsiflexed position, preventing nocturnal shortening of the fascia.
Footwear Advice & Orthotics: Assessing footwear and, if necessary, prescribing custom or off-the-shelf orthotics to optimize foot mechanics.
b) Achilles Tendinopathy: The Powerhouse Under Strain
What it is: Pain and stiffness in the Achilles tendon, which connects the calf muscles to the heel bone. It can occur mid-tendon (non-insertional) or at the heel bone attachment (insertional).
Key Symptom: Pain, stiffness, and tenderness above the heel, often worse in the morning or after exercise. The tendon may feel thick or swollen.
Pathophysiology: Similar to plantar fasciitis, Achilles tendinopathy is primarily a degenerative condition rather than purely inflammatory. Repetitive microtrauma without adequate recovery leads to changes in the tendon structure.
Risk Factors: Sudden increases in running or jumping, poor footwear, tight calf muscles, and biomechanical inefficiencies.
Exercise Thought's Approach: Our evidence-based strategy includes:
Graded Loading Program: Starting with isometric exercises (holding a calf raise) to reduce pain, progressing to concentric (lifting) and eccentric (lowering) loading. Heavy slow resistance training has shown excellent results in reorganizing tendon fibers.
Calf Strengthening: Crucial for power and shock absorption.
Activity Modification: Identifying and adjusting activities that aggravate the tendon.
Addressing Biomechanics: Analyzing gait and foot mechanics to reduce excessive strain.
c) Morton's Neuroma: The Nerve Impingement
What it is: A thickening or irritation of the nerve tissue, most commonly between the third and fourth toes, though it can occur between other toes. It's often caused by compression or irritation of the nerve.
Key Symptom: Sharp, burning pain in the ball of the foot, radiating into the toes. Patients often describe a feeling of a "pebble in their shoe" or numbness/tingling. Pain is typically worse with narrow shoes or prolonged standing.
Pathophysiology: Repetitive compression or stretching of the interdigital nerve, often due to biomechanical factors, tight footwear, or splayed toes.
Risk Factors: Wearing high heels, narrow-toed shoes, flat feet, bunions, and certain foot deformities.
Exercise Thought's Approach: Conservative management is usually highly effective:
Footwear Modification: Emphasizing wide-toed shoes, low heels, and avoiding pointed styles.
Metatarsal Pads: Placed behind the ball of the foot to spread the metatarsal bones and reduce pressure on the nerve.
Manual Therapy: To mobilize joints and reduce soft tissue tightness.
Custom Orthotics: To address underlying biomechanical issues like excessive pronation or splay.
Nerve Gliding Exercises: Gentle movements to encourage nerve mobility and reduce impingement.
2. The Biomechanical Blueprint: Posture's Role in Foot Pain
The foot is not an isolated unit; it is intimately connected to the entire kinetic chain. As Sam emphasizes, posture plays a critical role in the development and persistence of foot pain.
The Impact of the Kinetic Chain:
Pronation (Flat Feet): Excessive inward rolling of the foot can stretch the plantar fascia, rotate the tibia internally, and contribute to knee pain and even hip issues.
Supination (High Arches): A rigid, high-arched foot may have poor shock absorption, leading to increased impact forces on the heel and forefoot, often exacerbating plantar fasciitis or stress fractures.
Ankle Mobility: Restricted dorsiflexion (ability to lift the foot upwards) often forces compensation further up the chain, putting more stress on the plantar fascia or Achilles tendon during activities like squatting or walking.
Hip and Core Strength: Surprisingly, weak hip abductors or gluteal muscles can lead to compensatory pronation in the foot, as the body tries to stabilize itself. This underscores the holistic, full-body assessment we conduct at Exercise Thought in the Dandenong Ranges.
3. Diagnostic Precision: The Art of Clinical Assessment
Accurate diagnosis is paramount. At Exercise Thought, we combine detailed subjective history with thorough objective testing.
Key Diagnostic Tools:
Subjective History: Asking about the onset of pain, aggravating/easing factors, footwear, activity levels, and medical history.
Palpation: Precisely locating tenderness along the plantar fascia, Achilles tendon, or between the metatarsals.
Range of Motion Assessment: Checking ankle dorsiflexion, subtalar joint motion, and toe mobility.
Strength Testing: Assessing calf strength, intrinsic foot muscle strength, and gluteal strength.
Gait Analysis: Observing walking and running patterns to identify biomechanical inefficiencies.
Functional Testing: Having the patient perform activities that reproduce their pain (e.g., single-leg calf raises, hopping).
Differential Diagnosis: Ruling out other conditions like stress fractures, nerve entrapments (tarsal tunnel syndrome), or referred pain from the lumbar spine.
4. Treatment Philosophies: Beyond the Quick Fix
While injections or surgery may be options in severe, refractory cases, conservative management is the first and often most effective line of treatment.

FAQ: People Also Ask
1. What is the main cause of plantar fasciitis? Plantar fasciitis is often caused by repetitive strain and micro-tears in the plantar fascia, typically due to overuse, inappropriate footwear, excessive pronation (flat feet), high arches, or tight calf muscles.
2. Can orthotics really help with foot pain? Yes, custom or semi-custom orthotics can significantly help by providing support, correcting abnormal foot mechanics, distributing pressure evenly, and reducing strain on the plantar fascia or Achilles tendon. They are often part of a comprehensive treatment plan.
3. What is the difference between tendinitis and tendinopathy? "Tendinitis" implies acute inflammation, but most chronic tendon pain is actually "tendinopathy," which involves degeneration and disorganized collagen fibers. This distinction guides treatment, shifting focus from anti-inflammatories to load management and progressive strengthening.
4. How long does it take to recover from Morton's Neuroma? Recovery time varies, but with conservative management like footwear changes, metatarsal pads, and specific exercises, many people experience significant relief within a few weeks to a few months. Surgery is typically considered only after conservative methods have failed.
5. Why does my physiotherapist look at my hips when I have foot pain? Your physiotherapist assesses your entire kinetic chain because issues higher up (like weak hip muscles or poor knee control) can alter how your foot lands and pushes off, leading to increased stress and pain in your foot.
