Plantar Fasciitis

That first step in the morning

If the first few steps out of bed feel like you're walking on a bruised heel, and then it loosens up after a few minutes — that's the classic plantar fasciitis pattern. It's the most common cause of heel pain, roughly one in ten people will deal with it at some point, and it's one of the most frustrating conditions we treat because it can smolder for months when handled with the usual advice of ice, generic stretches, and waiting.

The plantar fascia is a thick band of connective tissue running along the bottom of your foot from heel to toes. It supports the arch and stores and returns energy with every step — it is, functionally, a spring you load with several times your body weight while walking, more while running. When its attachment at the heel becomes irritated and degenerated, you get a sharp, stabbing pain at the inside edge of the heel — worst with the first steps after rest, easing with movement, often returning as an ache by day's end.

Like the tendon problems it closely resembles, this is mostly degeneration under excess load rather than inflammation — which is why the modern term is plantar fasciopathy, and why anti-inflammatory approaches alone so often underdeliver.

Why it happens

Plantar fasciitis isn't just a foot problem. It's a loading problem.

Calf and ankle stiffness. Limited ankle dorsiflexion is one of the strongest measured risk factors. When the ankle can't bend far enough, the foot compensates by pronating more, which winds extra tension into the fascia on every step. Tight calves — the soleus especially — are almost always part of the picture, and the plantar fascia is functionally continuous with the Achilles system: a stiff calf pulls on the heel from both sides.

Weak foot intrinsics. The small muscles that support the arch decondition easily, especially in feet that live in supportive shoes. When they stop sharing the work, the fascia takes on stress it wasn't designed to handle alone.

Training and life-load errors. A jump in walking or running volume, a switch to minimalist shoes without an adaptation period, a new standing job, a long vacation walking on concrete. The fascia tolerates enormous load — but only load it was given time to adapt to.

Body weight and time on feet. Higher body weight and all-day standing occupations are both well-established risk factors; they simply raise the daily load count.

Upstream mechanics. A weak gluteus medius lets the knee collapse inward during gait, increasing pronation and loading the medial arch. This is why heel pain sometimes recurs even after successful local treatment — the source was never in the foot.

What else it could be

Most first-step heel pain is the fascia, but the mimics are worth naming. Fat pad atrophy hurts in the center of the heel, worse barefoot on hard floors, in older feet. Baxter's nerve entrapment — a small nerve pinched under the heel — can cause burning heel pain and accounts for a meaningful slice of "plantar fasciitis that never got better." Calcaneal stress fracture hurts with every step and with squeezing the heel, and needs a different plan entirely. S1 radiculopathy can refer to the heel. And heel pain in a teenager is usually the growth plate, not the fascia. In-office ultrasound sees the fascia directly — thickness, degeneration, tears — and helps sort this list in one visit.

One mimic that isn't: the heel spur. Spurs show up on X-rays of pain-free feet constantly, they're a consequence of traction rather than a cause of pain, and removing them is not the treatment for this condition. If a report mentioned one, you can stop worrying about it.

How we approach it

Treat the whole chain. OMM addresses restrictions in the foot, ankle, tibia, and pelvis that distort load distribution during gait. Restoring ankle dorsiflexion and normalizing foot mechanics often produces immediate, if partial, relief — and makes everything else work better.

Load the fascia on purpose. The best trial evidence for exercise here isn't gentle stretching alone — it's high-load strength training: slow, heavy calf raises with the toes propped up on a rolled towel, which tensions the fascia while it loads (the windlass mechanism). Done every other day with progressive load, this outperformed plain stretching in trials. It's the backbone of our program, alongside specific calf and plantar fascia stretching, which remains genuinely useful.

Shockwave therapy for the chronic cases — the ones that have hung on for months despite sensible care. Plantar fasciitis is among the best-evidenced uses of extracorporeal shockwave, with multiple randomized trials behind it. Most patients improve meaningfully across a series of three to five sessions, layered on top of the loading work.

Injections, with honest caveats. An ultrasound-guided corticosteroid injection provides real short-term relief for a severe flare — but the benefit fades by a few months, and steroid here carries two specific risks worth naming: fat pad atrophy and, uncommonly, rupture of the fascia. Guidance reduces the risk; restraint matters more. We use it as a bridge, seldom, and never serially.

Feet and shoes. Supportive footwear and over-the-counter arch supports reduce fascial strain while things calm down — useful early, especially for standing jobs. They're scaffolding, not cure: the exit plan is a foot strong enough and an ankle mobile enough not to need them.

When to seek care

Come in if heel pain has lasted more than two or three weeks, is worsening, or is changing how you walk — an antalgic gait sends the problem up the chain to the knee, hip, and back. Come in sooner if the pain is in the center of the heel, burns or tingles, hurts at rest or at night, or followed a jump in training in a runner (the stress fracture question). And if you've had "plantar fasciitis" for a year that never responded to anything — that's precisely the foot that deserves an ultrasound and a re-examined diagnosis.

What you can do right now

Stretch the calves properly: straight-knee for the gastrocnemius, bent-knee for the soleus, 30 seconds each, a few times daily. Add the specific fascia stretch — pull the toes back toward the shin and stretch the arch — before your first steps in the morning.

Start the loading: calf raises, slow tempo, with toes elevated on a rolled towel, building to single-leg and added weight, every other day.

Roll a frozen water bottle under the arch for comfort. Keep supportive footwear near the bed so the first steps of the day aren't barefoot on tile. Strengthen the foot's own muscles — short-foot exercises, towel scrunches — because the long-term fix is a foot that carries its own arch.

And keep moving. Total rest deconditions the spring; managed load rebuilds it.
