What Is Plantar Fasciitis?
Plantar fasciitis (pronounced plan-taarfa-shee-ai-tuhs) is one of the most common causes of heel and foot pain. It's caused by irritationswellingand pain in the thick band of tissue (or fascia) on the bottom of your foot that runs from your heel to your toes.
Plantar fasciitis and heel spurs
A heel spur (or bone spur) is a growth of bone on the bottom of your heelwhere your heel bone connects to your plantar fascia. Heel spurs may be caused by the stress and inflammation of plantar fasciitis. Over timeyour body responds to this stress and inflammation by building extra bone tissuewhich forms the heel spur. You may not know that you have heel spurs because they don't usually cause symptoms by themselves. Any symptoms you feel are likely caused by plantar fasciitis.
Symptoms of Plantar Fasciitis
Symptoms of plantar fasciitis include:
- Pain on the bottom of your foot near your heel
- Pain in the arch of your foot
- Swelling on the bottom of your heel
Plantar fasciitis pain
People with plantar fasciitis describe their pain as:
- Pain on the bottom of your foot that gets worse over time.
- Pain that is at its worst first thing in the morning or after they've been sitting for a long time. After a few minutes of walkingthe pain often decreases because walking stretches your fascia.
- A constant ache.
- Sharp or stabbing pain when you put pressure on your heel.
Plantar Fasciitis Causes and Risk Factors
Your plantar fascia help support your feet while you walkrunand perform activities like play sports. When your fascia are over strainedyou can get tiny tears on their surface. This brings on pain and inflammation.
You may be at greater risk of plantar fasciitis if you:
- Start a new sport or exercise program or ramp up your physical activity fast
- Do repetitivehigh-stress activities like running or dancing
- Spend many hours standing each dayespecially on hard surfaces
- Regularly wear shoes with poor cushioning or support
- Have flat feet or high arches
- Have tight calf muscles
- Overstretch the sole of your foot during exercise
- Have obesity
- Are 40-60 years old
Diagnosing Plantar Fasciitis
Your doctor will ask about your symptoms and check your feet to see if they can tell what's causing your pain. They'll be looking to see if you:
- Have flat feet or high arches
- Have a tender spot on the bottom of your foot in front of your heel
- Have limited range of motion when you flex your foot and try to pull your toes up toward your knee
- Don't have any symptoms that suggest another foot problemsuch as a heel stress fracture or Achilles tendonitis
Your doctor may also do some tests to make sure something else isn’t causing your problem. These tests generally include an X-ray. This can show if you have a bone fracture or arthritis . It can also show if you have heel spurs. If you doit suggests that you have had tension on your plantar fascia for a while. This happens quite often with plantar fasciitisalthough it doesn't usually cause symptoms itself.
Your doctor probably won't need to do other testsbut if they doit's likely to be another imaging testsuch as an MRI or ultrasound to look for fractures .
Plantar Fasciitis Treatment
Plantar fasciitis home remedies
This is likely the first treatment your doctor will recommend. These are simple steps you can take at home to reduce your pain.
Rest. Decrease or even stop doing the things that make your pain worse. For instancedecrease or stop doing activities where your feet pound on hard surfacessuch runningdancingor jumping. If you have serious painyour doctor may also suggest you use a walking boot and crutches for a few days to take the pressure off your foot and allow it to heal.
Change your exercise routine. For instanceswitch from a high-impact activitylike runningto a low-impact activity like cycling or swimming.
Stretch your feet and ankles. Tight muscles can make plantar fasciitis worse. Stretching can help you feel better and prevent the condition from getting worse.
Ice your arches. Put a water bottle in the refrigerator or freezer and roll it under your foot for about 20 minutes three to four times per day.
Plantar fasciitis brace
Your doctor may recommend you wear a night splintwhich keeps your foot flexed while you sleep. It can help relieve pain first thing in the morning.
Alsoif you have severe pain and wearing a walking boot isn't helpingyour doctor may also put your foot in a cast for a short time. This completely immobilizes your foot and allows it to heal.
Physical therapy
Your doctor may also suggest you work with a physical therapist. They can design a program to improve the function in your calf and foot. They may have you do stretchesspecialized ice treatmentsmassagesand other therapies to ease the inflammation in your plantar fascia.
Plantar fasciitis shoes
Don't wear shoes that are worn out or don't give good support.Wear shoes with thick soles and extra cushioning.A cushioned sole can help reduce the tension in your fascia that happens as you step and your heel strikes the ground. Replace your old athletic shoes before they wear out.
Inserts for plantar fasciitis
A cushioned insertsuch as a silicone heel padcan cushion your heel like a thick sole would. Your doctor may also suggest you get custom shoe inserts (orthotics) that you can use in all your shoes to take the pressure off your heel bone.
Plantar fasciitis stretches and exercises
A couple of stretches or exercises that work well to stretch your feet and ankles include:
Calf stretch. Put your hands on a wall with the knee on your affected leg straight and your heel on the ground. Place your other leg in front of this legwith your knee bent. Slowly and with controlpush your hips toward the wall to stretch your calf muscles and Achilles tendon. Hold this for 10 seconds and relax. Repeat 20 times on each foot. You should feel a strong pull in your calf while you stretch.
Plantar fascia stretch. This stretch helps to ease your pain in the morning before you get up from bed. While sittingcross your affected foot over the knee of your other leg. Grasp the toes this foot and slowly pull them toward you. If it's hard to reach your footwrap a towel or a yoga band around your toes to help pull them toward you. You should be able to feel your fascia like a tight band on the bottom of your foot with your other hand while stretching. Hold for 10 seconds and repeat 20 times on each foot.
Pain relief
Your doctor will likely recommend you take an over-the-counter (OTC) nonsteroidal anti-inflammatory drug (NSAID)such as ibuprofen or naproxen. Follow the directions on your package. In particulardon't take it for more than a month unless your doctor approves.
Plantar fasciitis healing time
Once you start treatmentyou’ll usually notice gradual improvementthough it can take up to 10 months for you to heal completely.
Other treatments
If less invasive methods don't workyour doctor may try:
- Cortisone injections. Cortisone is a powerful anti-inflammatory that can relieve your pain and inflammation. But your doctor may be cautious when using this because it can cause a tendon rupture or tear in your plantar fasciawhich may cause your arch to fall and cause chronic pain.
- Platelet-rich plasma injections. Platelet-rich plasma is taken from your own blood and injected into your plantar fascia. This seems to help the plantar fascia healand it doesn't have the same risk for tendon rupture that cortisone injections have. Howeverthis is still an experimental procedureand more research is needed to understand how it works. It also tends to be expensive.
- Ultrasonic tissue repair. This is a noninvasive therapy that uses high-energy sound waves to break up damaged tissue so that new tissue can grow to replace it. Your doctor may recommend this for ongoing plantar fasciitis.
- Electrocorporeal shockwave therapy. During this procedureyour doctor uses high-energy shockwave impulses to stimulate healing in your plantar fascia. This is another experimental technique that may or may not work. But since it's noninvasive and has low riskyour doctor may try it before you consider surgery.
- Surgery. 90% of people with plantar fasciitis get better without needing surgery. But if you've had treatment for 12 months and you haven't gotten betteryour doctor may recommend a couple of procedures: gastrocnemius recession or partial plantar fascia release. During a gastrocnemius releaseone of the muscles in your ankle (gastrocnemius) is lengthened to take pressure off your plantar fascia. During a partial plantar fascia releasethe surgeon makes a partial cut in your fascia to take the tension off your muscle.
