Plantar fasciitis—the most common cause of chronic heel pain—occurs when the thick ligament spanning the bottom of the foot becomes inflamed. A heel spur is a bony outgrowth at the plantar-fascia insertion; it is often present but not always painful. Accurate diagnosis of both conditions is essential because the majority respond to structured, non-surgical care when started early.
| Mechanical Over-load | Anatomic Contributors | Systemic & Lifestyle |
|---|---|---|
| Sudden hike in running mileage or standing time | Tight gastrocnemius–soleus complex limiting ankle dorsiflexion | Higher body-mass index |
| Unsupportive footwear on hard surfaces | Pes planus (flatfoot) or cavus (high arch) altering load | Occupations requiring long hours on concrete |
| Poor shock absorption in worn-out shoes | Rear-foot varus / over-pronation | Endocrine disorders (diabetes, thyroid) |
Microscopic tearing at the enthesis (bone–ligament interface) triggers inflammation; chronic traction can stimulate spur formation along the medial tubercle of the calcaneus.
| Conservative First-Line (≈ 90 % success) | Escalation / Procedural | Surgical (≤ 5 % of cases) |
|---|---|---|
| Calf-stretch & plantar-fascia stretch protocol (3 × day) | Custom orthotics with medial arch & heel cup | Endoscopic plantar fasciotomy (2-portal) |
| Night dorsiflexion splint or Strasburg sock | Extracorporeal shock-wave therapy (ESWT) (3-5 sessions) | Open plantar-fascia release with spur resection |
| Silicone heel pads or rocker-sole footwear | Ultrasound-guided platelet-rich plasma (PRP) or corticosteroid injection | Gastrocnemius recession if calf tightness drives recurrence |
| Short course NSAIDs; ice massage; activity modification | Low-level laser or radiofrequency micro-tenotomy (select cases) | — |
Most patients experience ≥ 50 % pain reduction within 4–6 weeks when daily stretching is combined with heel off-loading and orthotic support.
No. Many heel spurs are painless. Pain typically arises from the inflamed plantar fascia; spur removal is only considered if it impinges on soft tissue following failed conservative care.
A single, ultrasound-guided corticosteroid injection placed in the perifascial space (not inside the ligament) carries low rupture risk and can break the pain cycle for stubborn cases.
Once morning pain is ≤ 2/10 and calf flexibility is restored, a graded return (10 % weekly mileage increase) is allowed—often 6–8 weeks after treatment initiation.
Persistent heel pain is common but highly treatable. Schedule an evaluation with North Texas Podiatry Associates to confirm the diagnosis and begin a personalized, evidence-based plan for lasting relief.
