Plantar Fasciitis

What it is

Plantar fasciitis is irritation of the plantar fascia, the thick band of connective tissue that runs along the bottom of the foot from the heel to the base of the toes. It’s one of the most common causes of heel pain in adults, and one of the most often mismanaged.

The classic story: a sharp, stabbing pain at the heel with the first few steps out of bed in the morning, or after sitting for a while. It eases up as you walk and warm up, then returns later in the day, especially if you’ve been on your feet.

The good news: despite how stubborn it can feel, plantar fasciitis responds extremely well to the right treatment plan. The reason it lingers for months in many people is that the typical advice (“rest, stretch, get inserts”) addresses the symptom without changing the underlying load pattern.

What causes it

A few things commonly drive it:

• A change in load. A new running program, a job that suddenly has you on your feet, a long trip with new shoes, post-pregnancy weight shifts, a new gym routine.
• Calf and Achilles tightness. A stiff calf passes load onto the plantar fascia with every step. This is one of the biggest contributors and one of the most fixable.
• Foot mechanics. Overpronation, a high arch that doesn’t absorb shock well, or a stiff big toe joint can all overload the fascia.
• Hip and ankle weakness. When the hip and posterior chain don’t do their share of propulsion, the foot picks up the slack.
• Footwear and surfaces. Worn-out shoes, sudden barefoot work, and hard floors all change the load profile.

What it feels like

• Sharp, stabbing pain at the heel, particularly the first steps in the morning
• Pain that improves after the first 5 to 10 minutes of walking, then returns at the end of the day
• A deep ache along the arch
• Tightness in the calf and along the bottom of the foot
• Sometimes pain at the heel after long sitting

How we treat it

We treat plantar fasciitis as a load problem more than a tissue problem. A typical plan:

1. Calf and posterior-chain assessment. What’s stiff, what’s weak, where the load is getting stuck.
2. Manual therapy to the calf, plantar fascia, and surrounding structures, restoring mobility that’s been lost.
3. Dry needling to the calf and deep posterior leg muscles. Often dramatically effective for the trigger-point component that contributes to morning stiffness.
4. Progressive loading. This is the piece most people miss. The plantar fascia gets stronger by being asked to work, through specific calf raises (often heavy, slow, eccentric) and progressive walking or running tolerance.
5. Foot intrinsic strengthening to wake up the small muscles that should share load with the fascia.
6. Footwear and load coaching. What to wear, when, and how to scale activity back in without flaring it.

When dry needling helps

Dry needling is particularly effective for:

• Deep gastroc or soleus trigger points contributing to morning heel pain
• Tibialis posterior (deep posterior calf) tightness in pronators
• The muscles of the foot itself, particularly when the arch feels deeply tight or “knotted”

When to seek help

If heel pain has been around longer than two or three weeks despite stretching and rest, it’s worth getting evaluated. Plantar fasciitis that lingers for 6 to 12 months is almost always a case where the right treatment plan would have resolved it in 6 to 12 weeks. Earlier intervention dramatically shortens recovery.

Seek immediate medical care for any of the red-flag symptoms above, particularly a “pop” with sudden onset, which can indicate a fascia rupture or stress fracture rather than fasciitis.
