Plantar Fasciitis: How Painful It Gets and How to Calm a Flare-Up

If you’ve had plantar fasciitis, you know it can be surprisingly painful: a sharp, stabbing pain in the heel with your first steps out of bed, or after you stand up from your desk. It’s also one of the most common reasons people see a podiatrist. Here’s why it hurts the way it does, what makes it flare, and what you can do to calm it down.

How painful is plantar fasciitis?

Pain levels range from a dull ache after a long day to sharp pain that makes walking hard. The typical pattern:

• Sharp heel pain with the first steps in the morning
• Pain that eases as you walk around, then returns after sitting
• Aching after long periods on your feet or after exercise, rather than during it
• Tenderness on the bottom of the heel, toward the inside

Morning pain happens because the plantar fascia, the band of tissue that supports your arch, tightens overnight. Your first steps stretch it suddenly. (We cover that in detail in sharp heel pain in the morning.)

What causes a flare-up?

The American Academy of Orthopaedic Surgeons lists overuse, like too much running or jumping, and worn-out shoes as common culprits. Flare-ups often follow:

• A sudden jump in activity, like a new running plan or a long day of walking
• Standing for hours on hard floors
• Walking barefoot or in flat, unsupportive shoes or sandals
• Tight calf muscles or Achilles tendon
• Weight gain that adds stress to the feet

How to calm a plantar fasciitis flare-up at home

• Stretch before your first steps. Pull your toes back toward your shin with a towel for 30 seconds, a few times, before getting out of bed.
• Stretch your calves against a wall several times a day.
• Roll your arch over a frozen water bottle for 10–15 minutes to ease pain and inflammation.
• Wear supportive shoes, even at home, and avoid going barefoot on hard floors.
• Add arch support. A firm store-bought insert is a reasonable first step for many people.
• Back off high-impact activity for a bit; swap running for cycling or swimming while it settles.
• Use over-the-counter pain relievers short term, if they’re safe for you.

Most people improve with these steps, though it can take several months of consistency. The Mayo Clinic lists stretching and physical therapy, night splints and orthotics among the standard treatments.

When home care isn’t enough

See a podiatrist if heel pain lasts more than a couple of weeks despite home care, keeps you from walking normally, or comes with swelling, numbness or tingling. A proper exam also rules out other causes of heel pain, like a stress injury or a nerve problem.

At Opensky Podiatry, treatment for stubborn plantar fasciitis may include:

• A personalized stretching plan and footwear changes
• Custom orthotics when off-the-shelf support isn’t enough
• Night splints to keep the fascia stretched while you sleep
• Cortisone injections for short-term relief
• Shockwave therapy and PRP injections for pain that won’t quit

Surgery is rarely needed. See all your options on our heel pain and plantar fasciitis page.

Common questions

Should I keep exercising with plantar fasciitis?

Stay active, but switch to low-impact exercise like cycling or swimming during a flare. Return to running gradually once first-step pain is clearly better.

Do night splints help?

They can. A night splint holds the foot gently flexed while you sleep, so the plantar fascia doesn’t tighten overnight and morning pain is less sharp.

Can plantar fasciitis go away on its own?

It often improves over time, but without stretching, good shoes and support it can drag on for many months. Treating it early usually shortens recovery.

Is plantar fasciitis acute or chronic?

It can be either. It often starts as an acute flare after a change in activity. If it isn’t treated, the tissue can stay irritated for months and become a chronic problem, which is another reason not to push through the pain.

The bottom line

Plantar fasciitis can be very painful, but it’s also very treatable. Daily stretching, good shoes and arch support calm most flare-ups. If yours keeps coming back, a podiatrist can find what’s driving it and add the next level of care. Dr. Opensky sees patients in Skokie, IL and Whiting, IN.
