You can fix your own Plantar Fasciitis, but first you need to know what caused it

Updated: Dec 26, 2022



That pain in your heel may well be plantar fasciitis. It’s one of the top three sports injuries, after all.

The bad news is that this pesky condition is notoriously stubborn to treat, can take several months to resolve and there’s no one-size-fits-all wonder cure. It all depends on what caused it in the first place.

The good news is that you can fix it yourself with some simple equipment in most cases, if you can pinpoint the cause.

If you know what caused your plantar fasciitis, you also know how to treat it.

This article will help you to:

  • Know whether your heel pain is plantar fasciitis

  • Understand what your plantar fascia actually does

  • Figure out what might have caused your plantar fasciitis

Is your heel pain plantar fasciitis?

Clues that you may be suffering from plantar fasciitis: 

  • Pain and stiffness in the heel and/or inside arch of the foot (see picture below).

  • Pain when you put your foot down and walk first thing in the morning.

  • Your pain decreases with movement, but then increases if you spend too much time on your feet.

  • Increased pain when you walk after sitting still for a while.

  • When you press under your foot with your finger, you find a painful spot to the inside of the heel bone where the back end of the plantar fascia attaches. This painful area may extend into the arch of the foot (see picture below).

The plantar fascia runs under your foot and you feel the pain from plantar fasciitis where it attaches to your heel bone.

What the plantar fascia does

The first step to understanding the causes of plantar fasciitis is to get a basic idea of how the foot works.

The plantar fascia is a thick band of sinewy white tissue under the arch of your foot that runs from your heelbone to the ball of your foot.

It is part of a system in the foot and lower leg that keeps your body stable as you stand, walk or run. The system consists of muscles, tendons, bones, ligaments and the plantar fascia.

The role of the plantar fascia is to keep your foot from collapsing while there’s weight on the foot. Picture it as a cable that runs between the heel and the toes and tightens when you place weight on your foot. It also plays an important part in transferring load from the heel to the ball of the foot while you walk or run.

What causes plantar fasciitis?

Plantar fasciitis is caused when the load that the plantar fascia has to work against is too high, causing it to develop micro tears and inflammation.

The amount of force the plantar fascia has to deal with can be influenced by activity (running vs. walking), body weight, surfaces (grass vs. pavement), foot arch height (high vs. flat arches), muscle tension (tight calves) as well as weak muscles.

The injury can happen suddenly or over time through repetitive strain.

Common causes of plantar fasciitis:

  • The most common cause of plantar fasciitis I see in my clinic is when your shoes do not support your foot arch enough and you’re on your feet for a long time. Examples are a long shopping trip, going sightseeing in flip-flops while on holiday or running an endurance race.

  • If you gain a lot of weight it will increase the force through your feet and the plantar fascia will have to work harder to keep the foot arch from collapsing.

  • Your calves or other muscles in your legs are too tight.

  • If you suddenly take up running and overdo it, or if you do something like sprint to catch a bus while wearing the wrong shoes.

  • If you walk or run on very hard surfaces. Softs surfaces help to absorb some of the shock created when you run or walk, but if you do it on hard surfaces the plantar fascia has to deal with it all.

  • If other muscles in your lower body, all the way up to the muscles in your bum, aren’t strong enough and do not control the leg or absorb their share of the shock during running.

Now that you know what could cause your plantar fasciitis, let’s take a look at how to go about treating it yourself.
