Plantar Fasciitis: causes, treatment and when you need a specialist

If you're experiencing intense heel pain, especially when getting out of bed in the morning or after standing for extended periods, you're not alone. Plantar fasciitis is one of the most common conditions I treat in my clinic in Querétaro. Every year, thousands of patients in Mexico suffer from this condition that affects their quality of life, productivity, and daily activities. The good news is that most cases resolve successfully with proper treatment.

What Is Plantar Fasciitis?

The plantar fascia is a thick band of connective tissue that runs along the sole of the foot, from the heel to the toes. Its function is fundamental: it provides support to the arch of the foot and acts as a "shock absorber" when walking.

When this fascia becomes inflamed, the characteristic pain of plantar fasciitis develops. Imagine the fascia as a very tight rope or elastic band. If this rope is subjected to repeated stress, tiny tears form. These small tears create inflammation and pain, especially at the point where the fascia inserts into the heel.

It's estimated that plantar fasciitis affects about 10% of the population at some point in their lives, making it one of the most frequent reasons for orthopedic consultation for foot pain in Mexico. It's more common in middle-aged people and those with sedentary lifestyles, or paradoxically, in athletes.

Why Does It Appear? Risk Factors

Plantar fasciitis doesn't appear for no reason. In my experience as an orthopedic surgeon, I've identified several factors that significantly increase the risk:

• Age: More common between ages 40-60, though it can affect any age.
• Overweight or obesity: Extra weight increases tension on the plantar fascia. Every additional kilogram adds pressure.
• Profession or activities: People who stand for hours (teachers, salespeople, chefs) have greater risk.
• Intense exercise: Long-distance runners, jumpers, and high-impact athletes are susceptible.
• Improper footwear: Shoes without arch support or very high heels stress the fascia.
• Biomechanical problems: Flat feet, high arches, or excessive pronation alter force distribution.
• Calf tightness: Tight muscles limit foot mobility.

The Heel Spur Myth

This misunderstanding is very common. Some patients come to my office worried that they need to have the spur removed. The reality is different: by properly treating the fascia inflammation, the pain disappears, regardless of whether the spur is present or not.

Symptoms: When to Suspect Plantar Fasciitis

Typical symptoms of plantar fasciitis include:

• Sharp pain in the heel, especially when getting out of bed in the morning (characteristic morning pain).
• Pain that worsens after standing for prolonged periods.
• Temporary pain relief after walking for a few minutes.
• Severe pain after activities like running or climbing stairs.
• Feeling of tightness in the sole of the foot.

Warning signs that require immediate attention: If the pain is accompanied by severe swelling, redness, local heat, or if it appeared after direct trauma, consult immediately. These features could indicate other conditions that need quick evaluation.

Diagnosis

Plantar fasciitis diagnosis is primarily clinical. During consultation, I perform:

• History evaluation: when it started, what activities make it worse.
• Physical examination: heel palpation, Silfverskiöld test (assesses calf flexibility), gait analysis.
• Stretch test: passive toe extension that reproduces the pain.

In most cases, clinical assessment is sufficient. However, when there's doubt or the case is atypical, we use ultrasound or MRI to confirm the diagnosis and rule out other injuries like partial fascia tears or tarsal tunnel syndrome.

Treatment: The Therapeutic Ladder

Here's where I want to be very clear: 90% of plantar fasciitis patients improve with conservative treatment. They don't need surgery. The key is being consistent and patient.

I use what we call a "therapeutic ladder": we start with the simplest and least invasive options, advancing to more specialized options only if necessary.

Step 1: Conservative Treatment (First 6-8 weeks)

This is the first step and the most important:

• Relative rest: Reduce high-impact activities. Swimming, cycling, and gentle walking are excellent alternatives.
• Ice application: 15-20 minutes, 3-4 times daily, especially after activities.
• Anti-inflammatory medication: Anti-inflammatory medications as prescribed by your doctor.
• Orthotic insoles: Distribute pressure better and reduce fascia tension. Can be generic or custom.
• Appropriate footwear: Shoes with good arch support, moderate heel (no more than 2.5 cm), and cushioning.
• Fascia and calf stretching: Exercises 2-3 times daily.

Step 2: Specialized Physical Therapy (Weeks 2-12)

If there's no improvement after 2-3 weeks, I recommend specific physical therapy:

• Eccentric exercises: These special exercises have proven highly effective. They're based on stretching the fascia under load.
• Functional taping: Reduces arch movement and provides support.
• Therapeutic massage and myofascial release techniques.
• Postural correction: Improve walking mechanics.

Step 3: Advanced Treatments (Starting Week 8-12)

If conservative treatment isn't sufficient:

• Extracorporeal shockwave therapy (ESWT): Uses low-energy acoustic waves to stimulate repair. Efficacy: 60-70% in resistant cases. Requires multiple sessions.
• Steroid injection: Ultrasound-guided injection. Provides rapid pain relief, though temporary. Maximum 3 injections per year.
• Platelet-rich plasma (PRP) injection: More advanced biological therapy that promotes natural healing.

Step 4: Surgery (Less than 5-10% of Cases)

Only after failed conservative treatment for more than 12 months. Procedures include plantar fascia release, mostly minimally invasive in current practice.

Frequently Asked Questions

How long does plantar fasciitis take to heal?

With consistent conservative treatment, most patients experience significant improvement in 6-8 weeks. However, complete recovery can take 3-6 months. Some cases resolve in weeks, others require more time depending on severity and treatment adherence.

Do heel spurs cause the pain?

As I mentioned earlier, not necessarily. 50% of people with spurs feel no pain. The spur is a consequence of chronic tension, not the primary cause. Treating the fascia inflammation resolves the pain in most cases, with or without the spur.

Can I continue exercising with plantar fasciitis?

Yes, but with modified exercise. Avoid running, jumping, or high-impact activities while in the acute phase. Opt for swimming, cycling, gentle walking, or strengthening exercises. Activity helps, but excessive exercise worsens the condition.

Do orthotic insoles work?

Yes, they're very effective as part of conservative treatment. They distribute pressure better, reduce fascia tension, and improve foot biomechanics. Can be pharmacy orthotics or custom (usually more effective).

When do I need surgery?

Only when aggressive conservative treatment has failed for more than 12 months and pain seriously affects your quality of life. This occurs in less than 5-10% of cases. Current surgery is minimally invasive with excellent results.

Do shockwave treatments work?

Yes, with 60-70% efficacy in resistant cases. They're especially useful after 8-12 weeks of conservative treatment without improvement. They're non-invasive and allow quick return to normal activities.
