What plantar fasciitis is
The plantar fascia is a thick band of tissue running from the heel to the toes that supports the arch. Plantar fasciitis is irritation of that band, usually where it attaches at the bottom of the heel.
Typical signs
- Pain at the bottom of the heel, often toward the inside
- Worst with the first steps in the morning or after sitting
- Often eases after a few minutes of walking, then returns after long periods on your feet
Common contributing factors
- A sudden increase in walking, running, or standing
- Long shifts on hard floors
- Tight calf muscles or Achilles tendon
- Flat feet or high arches
- Worn-out or unsupportive shoes
- Weight gain
Not all heel pain is plantar fasciitis
Nerve irritation, a stress fracture, Achilles tendon problems, and thinning of the heel's fat pad can cause similar pain. That's why an exam matters before settling on a treatment plan. Heel spurs are common on X-rays, including in people with no heel pain at all.
Which visit to book
Book the Foot & Ankle Focused Pain Consultation and Treatment ($199). Custom orthotics are a separate package ($499).
When not to wait. If you can't put weight on your foot after an injury, have a wound, spreading redness, warmth, fever, or a foot that suddenly turns cold, pale, or dark, go to urgent care or an emergency department, or call 911. This clinic does not provide emergency care.
