Plantar Fasciitis That Won't Go Away: What to Do Next

Quick Answer

Most plantar fasciitis improves within 10 to 12 months of simple care, but a real minority of people still have pain after a year. If yours has not improved after about six months of consistent treatment, get the diagnosis rechecked and move up a planned ladder of options instead of repeating the same steps.

Most heel pain from plantar fasciitis fades within months. If yours has lasted six months, a year or longer, you are not imagining it, and you are not out of options. This page explains what a normal timeline looks like, what doctors mean by "chronic," and how to plan a next step that is more than repeating what has already failed.

How long plantar fasciitis usually lasts

The American Academy of Orthopaedic Surgeons (AAOS) says more than 90% of people with plantar fasciitis improve within 10 months of starting simple treatment. A 2019 review in American Family Physician gives a similar picture: about 80% improve within 12 months with nonsurgical care.

Those numbers are reassuring, but read them closely. Recovery is counted in months, not weeks, and some people are still hurting at the one-year mark. A 2018 study followed 174 patients for an average of almost 10 years after their symptoms began. At follow-up, 54% were free of symptoms and 46% still had some. Among the people who recovered, symptoms had lasted an average of 725 days, which is about two years. Everyone in that study had been diagnosed with the help of ultrasound, so the group may not represent milder cases that settle on their own.

The practical message: at month eight, slow progress is common. At month eighteen, it is reasonable to ask for a fresh look.

What "chronic" really means

There is no single official cutoff. In research, chronic or "recalcitrant" plantar fasciitis usually means pain that has continued for roughly 3 to 6 months or more despite treatment. A 2020 expert review in Foot & Ankle Orthopaedics uses 6 months of nonsurgical care as the point where additional procedures may be considered. The AAOS says surgery is generally saved for people who have not improved after 12 months of aggressive nonsurgical treatment.

The word describes how long the pain has lasted. It does not describe how damaged your foot is, and it does not mean the pain cannot improve.

Why some cases hang on

Several things tend to keep heel pain going:

The load on the fascia has not changed. Limited ankle motion from a tight calf, higher body weight and long hours of standing are recognized risk factors. If your job keeps you on hard floors all day, the tissue never gets a real break.
Treatment was started but not kept up. Stretching and strengthening programs in clinical trials ran for about two to three months of regular work. A few weeks of occasional stretching is not the same test.
The tissue itself has changed. Long-lasting plantar fasciitis behaves more like a worn, degenerated tissue than a simple inflammation. Our page on why plantar fasciitis becomes chronic explains the biology.
It is not plantar fasciitis, or not only plantar fasciitis. This is the one that most needs a doctor.

Two things did not predict a worse outcome in the 2018 long-term study: how thick the fascia looked on ultrasound and whether a heel spur was present. Women and people with pain in both heels were more likely to have lasting symptoms.

Get re-evaluated before adding more treatments

If your pain has lasted more than about three months and is not responding, imaging may help look for another diagnosis. A plain X-ray is usually the first study, and ultrasound or MRI can add detail. An MRI can help rule out a heel bone stress fracture or a tear in the fascia.

Ask for a re-evaluation, not just a refill of the same plan, if any of these apply:

Your pain is burning, tingling or electric, which points toward a nerve.
Your pain is worse the longer you are on your feet instead of worst with the first steps of the morning.
The sore spot has moved to the back of the heel, the middle of the arch or the center of the heel pad.
You have had no clear improvement after six months of consistent care.

Our guide to conditions mistaken for plantar fasciitis covers the look-alikes in more detail.

A sensible next-step ladder

Foot and ankle surgeons recommend fitting treatment to your symptoms, lifestyle and activity level instead of following one rigid sequence. Still, most care moves from simpler to more involved, roughly like this:

Redo the basics properly. In one study of 82 people who had already had heel pain for more than 10 months, a daily stretch aimed at the plantar fascia itself was taught to everyone. Two years later, 62 of the 66 people who responded (94%) reported less pain. In a separate trial of 48 patients, slow heel raises done every second day gave better results at 3 months than stretching, with no difference by 12 months. Supportive shoes and cushioned inserts belong here too.
Add supervised care. Physical therapy, orthotics and night splints are all on the AAOS list of nonsurgical treatments.
Consider an injection, with clear expectations. Cortisone tends to help for weeks, not months, and carries risks. See what to do when a cortisone shot did not work. The AAOS notes that more research is needed on platelet-rich plasma (PRP).
Consider shockwave therapy. A 2021 best practice guide suggests offering it to people who do not improve enough with core treatment. Trial results are mixed.
Consider a procedure. This is where embolization, needle-based procedures and surgery come in, usually after 6 to 12 months of real effort.

You do not have to try every rung. You do need an honest account of what you have tried, for how long and how consistently. Our heel pain guide gathers the detailed pages on each option.

Where plantar fasciitis embolization fits

Plantar fasciitis embolization (PFE) is a catheter procedure that reduces blood flow through the small abnormal vessels that can form around a chronically painful fascia. It is meant for long-lasting cases. In published studies, patients had usually failed at least 3 to 6 months of conservative care first. You can read how it is done on our plantar fasciitis embolization page.

The evidence is early. In a 2026 prospective series, 17 of 24 patients (70.8%) met the definition of a responder at 6 months. In a 2026 retrospective study, 8 of 11 treated patients (72.7%) had at least a 50% drop in pain at 6 months. These are small studies without comparison groups, and no randomized trial has been published. PFE has not been tested head to head against injections, shockwave or surgery, so no one can tell you it works better than those.

Dr. David Fox is a board-certified vascular surgeon who performs embolization for several joints and tendons. Our embolization guide explains the approach across the body. PFE is not right for everyone, and part of a consultation is confirming the diagnosis and checking that an artery procedure is safe for you.

When to be seen urgently

Long-lasting heel pain is rarely an emergency, but do not wait for a routine visit if you have:

A sudden pop or tearing feeling in the heel or arch, followed by bruising or swelling.
Pain so severe you cannot put weight on the foot.
Numbness, or a foot that turns cold or pale.
Fever, or redness and warmth that is spreading.
Deep pain at night or at rest that does not ease.
Swelling and tenderness in the calf.

Frequently Asked Questions

How long is too long for plantar fasciitis?

There is no fixed limit, but most people improve within 10 to 12 months of simple treatment. If you have had no clear improvement after about six months of consistent care, ask for a re-evaluation.

Can plantar fasciitis last for years?

Yes. In a 2018 study that followed 174 patients for an average of almost 10 years, 46% still had symptoms at follow-up. That study only included people diagnosed with ultrasound, so it may not reflect milder cases.

Does a heel spur mean my plantar fasciitis will not heal?

Not according to the long-term data. In the same 2018 study, having a heel spur at the start had no effect on how patients did over time.

Do I need an MRI if my heel pain will not go away?

Not always. Imaging is mainly used when pain lasts longer than about three months without responding, or when the symptoms do not fit the usual pattern. X-ray is usually first, and ultrasound or MRI can follow.

Is embolization the next step after everything else fails?

It is one option for long-lasting cases, alongside others such as shockwave therapy, needle-based procedures and surgery. The research on embolization is early and comes from small studies without comparison groups.
