Plantar fasciitis (say "PLAN-ter fash-ee-EYE-tus") is the most common
cause of heel pain. The
plantar fascia is the flat band of tissue (ligament) that
connects your heel bone to your toes. It supports the arch of your foot. If you
strain your plantar fascia, it gets weak, swollen, and irritated (inflamed). Then your heel or the bottom of your foot
hurts when you stand or walk.
Plantar fasciitis is common in
middle-aged people. It also occurs in younger people who are on their feet a
lot, like athletes or soldiers. It can happen in one foot or both feet.
is caused by straining the ligament that supports your arch. Repeated strain
can cause tiny tears in the ligament. These can lead to pain and swelling. This
is more likely to happen if:
Most people with plantar
fasciitis have pain when they take their first steps after they get out of bed
or sit for a long time. You may have less stiffness and pain after you take a
few steps. But your foot may hurt more as the day goes on. It may hurt the most

for everyone with plantar fasciitis. But there are many things you can try to
help your foot get better:
If these treatments do not help, your doctor may recommend
splints that you wear at night, shots of
medicine (such as a steroid) in your heel, or other treatments.
You probably will not need surgery. Doctors only suggest it for people who
still have pain after trying other treatments for 6 to 12 months.
Plantar fasciitis most often occurs because of injuries that have
happened over time. With treatment, you will have less pain within a few weeks.
But it may take time for the pain to go away completely. It may take a few months to a
Stay with your treatment. If you don't, you may have
constant pain when you stand or walk. The sooner you start treatment, the
sooner your feet will stop hurting.

Exactly what causes
plantar fasciitis is not well understood. But it
probably develops as the result of repeated small tears in the
plantar fascia. Normally when you walk, your plantar fascia stretches as your
foot strikes the ground. If the plantar fascia is strained by the way you walk
or by repeated stress, it can become weak, swollen, and irritated (inflamed), and
it can hurt when you stand or walk.
Conditions or activities that
may lead to plantar fasciitis include:
The classic symptom of
plantar fasciitis is heel pain when you take your
first steps after getting out of bed or after sitting for a long period of
time. You may also have:
Plantar fasciitis may be mistaken for
other conditions with similar symptoms, such as arthritis or a nerve problem such as
tarsal tunnel syndrome.
Plantar fasciitis usually develops gradually. You may have heel pain only when
you take your first steps after getting out of bed or after sitting for a long
period of time. If you do not rest your feet, the pain will get worse. Other
things, such as the repetitive stress of walking, standing, running, or
jumping, will add to the injury,
inflammation, and pain. The injured ligament may never
heal completely if you are not able to stop the activity or change the
condition that caused it.
As plantar fasciitis progresses:
If the condition is not treated, plantar fasciitis can
cause constant heel pain when you stand or walk.

shaped, or your training routine.

plantar fasciitis, your doctor will ask questions
about your symptoms and your past health. He or she will also do a
physical exam of your feet that includes watching you
stand and walk.
X-rays aren't helpful in diagnosing plantar
fasciitis, because they do not show ligaments clearly. But your doctor might
take X-rays if he or she suspects a
stress fracture, bone cyst, or other foot or ankle
bone problems. X-rays may show whether a
heel spur is present, but a bone spur does not

suspects nerve entrapment, you may have neurological testing.
The goals of treatment for
plantar fasciitis are to:

pain with nonsurgical treatments. Only about 5 out of 100 need surgery.footnote 1
that you start when you first notice symptoms is more successful and takes less
time than treatment that is delayed.
There are many methods you can
try to relieve the heel pain of
plantar fasciitis. Even though their effectiveness has not
been proved in scientific studies, these methods, used alone or in combination,
work for most people.footnote 2
Avoid using only heat on your foot, such as from a
heating pad or a heat pack for at least the first 2 or 3 days. Heat tends to make symptoms worse for some people. If you use
contrast baths, which alternate hot and cold water,
make sure you end with a soak in cold water. If you try a heating pad, use a low setting.
If your weight is
putting extra stress on your feet, your doctor may encourage you to try a

rest, ice, and stretching exercises help relieve your

you have not improved after 6 weeks, your doctor may recommend that you
continue those methods but add other nonsurgical treatments, such as:

consider surgery only for severe cases that do not improve.

plantar fascia release surgery. Plantar fascia release
involves cutting part of the plantar fascia ligament in order to release the
tension and relieve the inflammation of the ligament.
If you are trying to lose
weight and you develop plantar fasciitis when you begin exercising, especially
jogging, talk with your doctor about other types of activity that will support
your weight-loss efforts without making your heel pain worse. An activity like
swimming that doesn't put stress on your feet may be a good choice.
If your plantar fasciitis is related to sports or your job, you may have
trouble stopping or reducing your activity to allow your feet to heal. But
resting your feet is very important to avoid long-lasting heel pain. Your
doctor or a
sports medicine specialist may be able to suggest a
plan for alternating your regular activities with ones that do not make your

whether physical therapy or referral to a sports medicine
orthopedist is appropriate.
Some questions you may want to ask about exercise include:
The following steps will help prevent
plantar fasciitis or help keep the condition from
getting worse if you already have it:
If you feel that work activities caused your heel pain, ask
your human resources department for information about different ways of doing
your job that will not make your heel pain worse. If you are involved in
sports, you may want to consult a sports training specialist for training and
conditioning programs to prevent plantar fasciitis from recurring.
The first steps your doctor will
recommend to treat
plantar fasciitis are ones you can take yourself.
Different people find that one method or a combination of methods works best
Try the following methods:
Often athletes develop foot problems because they train in
shoes that are worn out or don't fit properly. Replace your shoes every few months, because the padding wears out. Also, replace shoes if the tread or heels are worn down. While replacing shoes is expensive, it is less expensive-and less painful-than a long-lasting heel problem. Other
sensible training techniques, such as avoiding uneven
or hard surfaces, can help prevent plantar fasciitis from occurring or

your doctor may encourage you to try a weight-loss program.
successful at treating plantar fasciitis, you will need to:
The healing process takes time-from a few months to a
year. But you should begin to have less pain within weeks of starting treatment.
If you have not improved after trying these methods for 6 weeks, your doctor
will suggest other treatments.
Your doctor may recommend medicine to
relieve the pain and
inflammation caused by
plantar fasciitis. Drug treatment does not cure
plantar fasciitis. But by reducing pain, medicine may make it easier for you to
follow other treatment steps, such as stretching. You should not use
medicine as a way to continue the activities that are causing heel
Medicine options include:
Injections of botulinum toxin are being studied for use in plantar fasciitis.
Surgery is usually not needed for
plantar fasciitis. About 95 out of 100 people who have
plantar fasciitis are able to relieve heel pain without surgery. Your doctor
may consider surgery if nonsurgical treatment has not helped and heel pain is
restricting your daily activities. Some doctors feel that you should try
nonsurgical treatment for at least 6 months before you consider
types of surgery for plantar fasciitis are:
Experts in the past thought that heel spurs caused plantar
fasciitis. Now experts generally believe that heel spurs are the result, not
the cause, of plantar fasciitis. Many people with large heel spurs never have
heel pain or plantar fasciitis. So surgery to remove heel spurs is rarely
Physical therapy may
be helpful for some people who have
plantar fasciitis. It can be especially useful for
people who have problems with foot mechanics (biomechanical problems), such as
A technique called
extracorporeal shock wave therapy (ESWT) uses pulsed sound waves to treat
plantar fasciitis. Research is still being done, but some studies show that ESWT can help reduce symptoms in plantar fasciitis that has not responded to other treatment.footnote 3, footnote 4 New shock wave
treatments are being studied. Most types of shock wave therapy, sometimes
called "focused" ESWT, require anesthetic. Another type, called radial ESWT,
can be done without anesthetic, because the shock wave is more spread
