Can I Run with Plantar Fasciitis?

Dear MyRunningDoc,

I am a runner who has been suffering with plantar fasciitis for several months. I tried couple of different things myself to get the heel pain to go away but it still continue to bother me. When I went to see my doctor, she told me that I had to stop running.

Can I run with plantar fasciitis? Will my heel pain get worse if I keep running? Or can I run with plantar fasciitis and still heal.

Hello John,

Heel pain can be frustrating when you are a runner. It isn't that the heel pain is so debilitating that it stops you from running, but that you are often distracted by it, and concern that the problem will get significantly worse or translate into other overuse injuries.

Plantar fasciitis of course is the most common form of heel pain. But it isn't the only type of heel pain that happens in runners. The short answer is that if it is only plantar fasciitis, you can probably keep running without the problem getting worse. It is also possible to continue running and still heal your heel pain.

This all assumes that you have been correctly diagnosed, and have not been mis-diagnosed. If your doctor mistakenly diagnoses you with plantar fasciitis, when in fact have a calcaneal stress fracture (crack in the heel bone), or a partial rupture of the plantar fascia (a small tear in the plantar fascia), you will have to stop running for some period of time, depending upon the severity of the condition.

It is important to note that stopping running alone will not cure any of the above mentioned causes of heel pain. conditions. Many runners can self-diagnose their heel pain without ever seeing a doctor. But if you have any doubt about the accuracy of your diagnosis, or specifics about how to continue running while you have plantar fasciitis, you should seek a second opinion from a sports medicine podiatrist who specializes in the treatment of runners.

Heel Blister: To Pop or Not To Pop?

 

Hi Dr. Segler,

I've had this blister on my heel for the past three days and it has gotten slightly larger.  I'm wondering if I should allow more time for it to heal or pop, drain, etc?  What's the fastest way to get it healed?

Sincerely,
Ryan M.

Answer:

Hello Ryan,

A blister on the inside of the heel can be painful when running or even walking.  If you are currently training for a marathon, the last thing you want to do is stop running just because you have a blister on your heel.  But obviously the blister has to stop getting bigger before it is going to heal.

There are only a couple of reasons that a blister continues to get bigger.

1. Friction. If you are continuing to rub the inside of the heel in the same way that cause the blister to form in the first place, the blister will continue to get bigger.

2. Compression. If you repeatedly press on the blister,  the fluid with in the blessed blister will try to disperse outward. Since the fluid is all contained inside the blister, this will continue to separate the layers of the skin from the pressure applied to the blister when the fluid tries to move. This causes the blister to continue to enlarge.

The redness at the border of blister tells me that the fluid is being compressed and further separating the layers of the skin (indicated by red arrows). This of course hurts and makes the heel blister bigger.

If you pop or drain the blister, it will increase the risk of infection. If you pop (or drain) the blister it will feel slightly better in the short term, but it might take slightly longer to completely heal.  As long as all of the irritation to the blister is removed, your body will resorb the blister fluid and heal the blister.

The blister in these images appears to be flat enough that it could be offloaded with some simple pads that could be obtained from a local pharmacy.  The idea is to place felt pads around the blister. By removing the pressure that is being applied to the blister when you walk, it will stop enlarging and it will start to calm down.

If a pad is applied to the heel, it will place all of the pressure around the blister, instead of on the blister. This will significantly decrease both the compression and friction of the blister.  If the oval pads that you find at the pharmacy are not large enough, you can simply cut two of them in half and then apply two separate half-oval pads to completely surround and protect the blister.

Here is an image of the proper pad placement with the red area indicating a blister:

Once the blister has completely healed your next task will be to identify the cause of the blister.  Obviously will not want this to happen again. If you have just gotten a new pair of shoes you want to make sure to break and then more gradually the next time. If your shoes were to loose, obviously want to tie them slightly tighter so that your heel isn't sliding around inside the running shoe. And if the blister happened after running a race (where you were dumping water on your head to stay cool) or from running in the rain, you want to make sure that you avoid getting your feet as wet the next time.

Heal that heel fast so that you can get back to running!

Marathon Blister. Should I pop it?

Question:
Hi MyRunningDoc!


I have been reading your site. This blister formed on my heel yesterday. It is huge and painful. I am running in the Avenue of the Giants Marathon on May 5, 2013 and really can't take a break from marathon training. Should I pop it?

Thanks!
W.H., San Francisco CA

Answer:
Thank you for your inquiry! That is certainly a Giant of a marathon blister. I can see how that would hurt and put a damper on your final marathon training.

There is always an advantage and a disadvantage to draining in any blister on the foot that pops up during training.

With a blister that large and a marathon that close, it is unlikely that you would be able to run the marathon without significant pain. In fact the blister is so big it would probably pop during the marathon anyway.

With most small blisters, it is typically better to let them go away on their own. If you do not drain a small blister and can keep it from getting rubbed when you are running, the fluid will gradually recede and the blister will re-adhere. It will eventually peel away revealing healthy skin underneath. It is also the least likely to get infected because you don't open the blister allowing bacteria to get inside the skin.  This actually will heal the fastest and is the safest approach.

Things get tricky when a running blister on the foot gets big.

When you have a big running blister that causes a great deal of discomfort when you run, it actually hurts because the fluid is getting pushed and compressed.  If you step on a water balloon, the balloon will squish outward under your foot. The balloon will push out and stretch as far as it can unless it pops.

So when you run on a blister like this one pictured here, the blister fluid actually pushes and continues to separate the layers of skin at the edge of the blister. This of course causes more irritation and more fluid accumulation, making the blister even bigger as you continue to run.  The only way to stop this process is to stop irritating the blister on the foot. One way to do this of course is to stop running.

If you can pad the blister and keep the pressure off of it you might be able to continue training without the blister getting any bigger.  That would be hard to do given the location of this blister on the inside of the foot and heel. It will be almost impossible to remove all the pressure from the heel inside the running shoe.

If you pop the blister, it will hurt more for the first day or two.  You can decrease the amount of discomfort by using moleskin or another type of blister cover that will stop the friction from rubbing the overlying skin. It may also be helpful to put some padding around the blister in order to decrease irritation.

If you decide to pop your blister, it is always best to drain the blister by making a small hole at the bottom edge of the blister down toward the bottom of the foot so that the fluid will continue to drain downward and out of the blister as it re-accumulates. Typically some more blister fluid will accumulate inside the blister for several days after you pop it.

The skin on the top of the blister is not what is painful. It is the skin underneath. Some people start to drain the blister and realize this and then trim off the entire top of the blister. If you are to do that in this case, it would leave an open sore about the size of a half dollar. This would of course leave an enormous raw spot that would be very painful whenever you run during training. You foot would be killing you during the marathon.

In these types of cases it is often better to simply drain the blister and leave the top of the blister intact to function as a biologic dressing. This will take slightly longer to heal than if you don't drain the blister.  However this assumes that you are of course going to continue to run, train and complete the marathon that you have planned.

It would be best to be evaluated in person or by a podiatrist or arrange a remote consultation with a running injury expert in order to get more detail, before making your final decision.  You can also learn more about blisters from running by clicking here.

San Francisco Podiatrist on Difference Between Heel Pain and a Heel Spur

Heel pain is the most common form of foot pain that causes people in San Francisco to make an appointment with a podiatry clinic. In fact, nationwide, about 40% of all visits to podiatrists are due to heel pain diagnosed as plantar fasciitis. As a podiatrist in San Francisco myself, the thing that I find interesting is that most people with plantar fascitis think they must have a heel spur to have heel pain. But that’s not always true.

So what is the difference between plantar fasciitis and a heel spur?

To begin with, let’s explain how to tell if you have plantar fasciitis. Anyone with plantar fasciits will have pain in the bottom of the heel or in the arch. In most cases this pain is worse when you get up and step out of bed in the morning. The heel may also hurt when you get up from your desk after working at a computer for a couple of hours.

As you start to walk, the first step is usually a sharp pain or sudden ache in the bottom of the heel. After a few steps, the heel pain starts to subside and feels better. In many cases, it may not even hurt at all while you are walking around or even running. But when you sit still and get back up again to start walking, that’s when the heel pain returns.

If you have this kind of morning heel pain and simply push on the bottom of the heel (and it hurts) you most likely have plantar fasciitis.

Many people in the San Francisco Bay Area seem to believe that heel pain is due to a sharp heel spur poking down and causing pain. But in fact about half of all people who have this kind of heel pain don’t have a heel spur at all. And about half of people with no heel pain, happen to have a heel spur that will show up on x-ray. So the two problems aren’t necessarily related.

The most common cause of heel pain is plantar fasciitis, which is simply inflammation of the plantar fascia. The plantar fascia is a big ligament attaching to the bottom of the heel and extending out to the toes. If you put too much stress on the plantar fascia, it can become inflamed where it attached to the heel bone.



With improper biomechanics, such as excessive pronation (flat feet that roll inward as the arch collapses) the plantar fascia ligament may tug away at the heel bone. With tension applied to the plantar fascia, the attachment may cause the heel spur to form.

The way this happens is that the ligament pulls the covering (called the periosteum) of the heel bone away. A small blood clot forms and then becomes calcified as it heals. If this happens again and again, the heel spur gradually grows. Because the heel spur is caused by the pulling on this big ligament, you can understand why a heel spur points out toward the toes and not down toward the ground.




Any podiatrist in San Francisco can simply take an x-ray of your heel to tell whether or not you have a heel spur. But the reality is, it doesn’t matter.

In the last 7 years, I have only surgically removed 2 heel spurs. Both of them were broken and wouldn’t heal. One was an young ironworker in San Francisco who fell off some scaffolding while working on the Golden Gate Bridge retrofit project. The other was a woman in her sixties who has some osteoporosis and broke the heel spur while doing high impact aerobics.

But most people with plantar fasciitis can get better on their own, even if they have a heel spur. In the vast majority of cases, spending a few minutes doing our San Francisco Podiatry Heel Pain Recovery Stretches will make the heel pain go away. The spur just simply doesn’t usually need to be removed in surgery.

Dr. Christopher Segler is a nationally recognized expert on conditions affecting the heel bone. In 2006 he was awarded 1st Place at the National Meeting of the American Podiatric Medical Association for his research on diagnosing heel bone infections with magnetic resonance imaging (MRI). He offers podiatry house calls in San Francisco for busy athletes and people who just think it is ridiculous to take half a day off work just to see a foot doctor.
