Plantar fasciitis is one of the most common causes of foot pain that I see in my Houston podiatry office. The pain usually starts when you first step out of bed in the morning. Some people describe it like walking on broken glass. Others say there’s a hot poker sticking into their heel. No matter how you describe it, it hurts!
How Plantar Fasciitis Develops
The plantar fascia ligament attaches to your heel. It extends through the bottom of your foot towards your toes. The plantar fascia ligament is important for the stability and support of your feet.
As you walk, the plantar fascia flexes to act as a shock absorber. That means that every step you take, the plantar fascia ligament pulls on your heel. This repetitive pulling is what causes plantar fasciitis. The plantar fascia becomes inflamed where it attaches to the heel bone. This leads to the heel pain associated with plantar fasciitis.
Where Does Plantar Fasciitis Hurt?
Plantar fasciitis is the most common cause of heel pain. This is due to the plantar fascia ligament pulling on your heel every step you take. You may feel intense heel pain with your first steps out of bed in the morning. This pain often decreases as you walk. It can come back again after you’ve sat for a period of time or at the end of the day. If plantar fasciitis gets bad enough the pain may not go away throughout the entire day.
Plantar fasciitis does not only have to affect your heel. The ligament extends through the entire sole of your foot. Sometimes it causes arch pain only. Or it may cause both heel and arch pain. In fact, there are many ways for pain from plantar fasciitis to present. Heel pain caused by plantar fasciitis is the most common presentation.
How Plantar Fasciitis is Diagnosed
When you come into my Houston podiatry office with suspected plantar fasciitis, I’ll take an x-ray. I do this for a couple of reasons. First, there are other causes of heel pain that we have to make sure you don’t have. For instance, if you have a stress fracture in your heel, it is very important that it is found. The treatment for a stress fracture of the heel bone is treated much differently. I also take an x-ray to check to see if a heel spur has developed.
In addition to an x-ray, I may use a diagnostic ultrasound to look at the plantar fascia ligament itself. When the ligament is inflamed, I’m able to see it thickening on the ultrasound. The ultrasound is also useful if I have to give you an injection. It allows me to place the medication exactly where the inflammation is.
In cases where your heel pain does not resolve as expected with treatment, I may order an MRI. This gives a more detailed image of the bone and soft tissue. It allows me to see if there is anything other than plantar fasciitis causing your pain. It will also detect damage to the ligament, known as plantar fasciosis. Most cases of heel pain do not need an MRI.
Are Plantar Fasciitis and Heels Spurs the Same?
Plantar fasciitis and heel spurs are associated, but they are not the same. In fact, some refer to plantar fasciitis as Heel Spur Syndrome.
A heel spur is a bone spur that forms on the bottom of the heel bone. It forms because of the tension of the plantar fascia ligament as it pulls on your heel bone. The bone spur forms in response to that tension. It is a symptom of overuse of the plantar fascia. Not every case of plantar fasciitis has a heel spur.
If a heel spur is present on x-ray, it gives me valuable information about the mechanics of your feet. The heel spur is rarely the source of pain. Because you have a heel spur does not mean that it has to be removed surgically. In fact, less than 5% of heel spurs needs foot surgery to treat them.
Plantar Fasciitis Treatment
Stretching is important to helping to resolve plantar fasciitis. There are two stretches that are helpful. First, rolling a ball, rolling pin, or frozen water bottle through the arch of the foot. This mobilizes the plantar fascia. Stretch out your foot before you get out of bed in the morning. You may be able to calm down the pain you feel when you first get up.
The other important stretch is a calf stretch. This will stretch your Achilles tendon. It also helps to stretch your plantar fascia. You can stretch against a wall. You also can use a towel to pull back your foot when you’re sitting. Hold each stretch for a slow ten count.
The pain from plantar fasciitis is due to the inflammation of the ligament. It makes sense that anti-inflammatory medication is useful to treat the inflammation. As the inflammation reduces, so does the pain.
I use anti-inflammatory medication in one of two ways. I can locally pinpoint the inflammation. It makes sense to use a treatment that also works at the point of inflammation. A corticosteroid injection is the preferred way to deliver the medication. An injection allows the medicine to be dropped right at the point of inflammation. An injection may not be the best treatment for you. In that case, a course of oral anti-inflammatory medication will be used.
Anti-inflammatories will manage the inflammation. You also need something to manage the cause of the inflammation. This is the mechanical pull of the plantar fascia ligament. It makes sense that you need to limit the pull of the plantar fascia. A medical-grade insole will support the ligament. This allows the anti-inflammatory to work better. I carry these medical-grade insoles in my Houston podiatry office.
Plantar fasciitis often causes a sharp stabbing pain in the heel when you get out of bed in the morning. This is because your plantar fascia ligament contracts and shortens while you sleep. When you step out of bed, it is stretched and becomes inflamed again.
A night splint is a brace that you wear in bed. The splint keeps your foot in a flexed position while you sleep. This prevents the ligament from shortening. You will likely feel reduced pain when you step out of bed after wearing night splint while you sleep.
A custom orthotic is a specialized insole. It is made to provide support and efficiency to your foot and ankle. It is more than an insole that provides arch support. A custom orthotic is designed to correct your foot mechanics. This allows your foot to function in a more stable way. It will also prevent the overuse of your plantar fascia ligament. This will allow the inflammation causing your foot pain to decrease. It will also prevent its return.
Not all custom orthotics are created equal. In my Houston podiatry office, I perform a complete biomechanical examination. I also watch you walk so I can do a proper gait analysis. These elements are crucial to make the perfect custom orthotic for you. I then take a mold of your feet while maintain them in the most stable position. If your custom orthotics weren’t made this way, it’s time for you to come in for an update.
Regenerative medicine is one of the newer treatments for a soft tissue inflammation. It is very successful to treat plantar fasciitis. These includes platelet rich plasma (PRP), amniotic stem cell injections, and exosome cell injections.
These injections help to reduce inflammation. They also contain growth factors to help to repair the damaged tissue. I find that using these injections help you to make a more complete and lasting recovery.
The Tenex procedure is a minimally invasive procedure done in the operating room. I use diagnostic ultrasound to image the inflamed plantar fascia ligament. A very small incision is made and a probe is inserted into the damaged ligament. The tip of the probe vibrates rapidly using ultrasonic energy. This breaks up the inflamed tissue. The broken up tissue is removed with suction.
This procedure is performed under anesthesia but there is little down time afterwards. You don’t even need to wear a special surgical shoe after. You’re able to walk immediately after the procedure. You’ll see the full results of the Tenex procedure within six weeks.
Will Plantar Fasciitis Come Back?
It is a relief when your pain goes away with treatment for plantar fasciitis. But the job is only half done. The inflammation has reduced and the pain followed suit. Unfortunately the mechanics that caused your heel pain to form is still the same. Those mechanics need to be addressed so the painful condition doesn’t come back.
Your plantar fascia pain may have gone away quickly with using medical-grade insoles. In that case, keep wearing them. Those insoles will provide support for the plantar fascia ligament. That will help to limit the pull of the ligament.
It may have taken a longer time to treat your foot pain. You likely need more mechanical control than medical-grade insoles provide. In these cases, I’d suggest the use of a custom orthotic. A custom orthotic is the best long term treatment for plantar fasciitis. It is the best way to prevent plantar fasciitis from coming back.
Evaluating you for a custom orthotic is more involved than you’d think. I do a comprehensive biomechanical examination with a gait analysis. This lets me know how your foot is functioning when you’re walking. I then take a mold of your foot in a stable, neutral position. I create a prescription to make the custom orthotic. This will make your feet as stable and efficient as possible.
When Plantar Fasciitis Won’t Go Away
You may reach a point when all conservative measures have been exhausted. It is then time to consider surgery to treat plantar fasciitis. Like any surgery, it should be a last resort. Surgery involves releasing the plantar fascia ligament from the heel bone. If you have a heel spur, I will remove that as well.
In most cases, you will be able to walk in a surgical shoe after your surgery. You can return to full activity 8 to 12 weeks after surgery. After surgery for plantar fasciitis, it is crucial that you use a custom orthotic. This is because your plantar fascia is released and no longer has function. An orthotic will provide the support and stability to your foot.
