Plantar fasciitis is one of the most common sources of heel pain. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and
extending along the sole of the foot towards the toes. Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes
inflammed it is known as plantar fasciitis.
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body's weight, and the foot flattens and
this places a great deal of pressure and strain on the plantar fascia. There is very little elasticity to the plantar fascia, so as it stretches only slightly; it pulls on its attachment to the heel.
If the foot is properly aligned this pull causes no problems. However, if the foot is "pronated" (the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch
falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with "supination"
(the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively in flexible; usually have a high arch, and a short or tight plantar fascia. Thus as
weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel.
Plantar fasciosis is characterized by pain at the bottom of the heel with weight bearing, particularly when first arising in the morning; pain usually abates within 5 to 10 min, only to return later
in the day. It is often worse when pushing off of the heel (the propulsive phase of gait) and after periods of rest. Acute, severe heel pain, especially with mild local puffiness, may indicate an
acute fascial tear. Some patients describe burning or sticking pain along the plantar medial border of the foot when walking.
Your doctor will ask you about the kind of pain you're having, when it occurs and how long you've had it. If you have pain in your heel when you stand up for the first time in the morning, you may
have plantar fasciitis. Most people with plantar fasciitis say the pain is like a knife or a pin sticking into the bottom of the foot. After you've been standing for a while, the pain becomes more
like a dull ache. If you sit down for any length of time, the sharp pain will come back when you stand up again.
Non Surgical Treatment
Usually, the pain will ease in time. 'Fascia' tissue, like 'ligament' tissue, heals quite slowly. It may take several months or more to go. However, the following treatments may help to speed
recovery. A combination of different treatments may help. Collectively, these initial treatments are known as 'conservative' treatments for plantar fasciitis. Rest your foot. This should be done as
much as possible. Avoid running, excess walking or standing, and undue stretching of your sole. Gentle walking and exercises described below are fine. Footwear. Do not walk barefoot on hard surfaces.
Choose shoes with cushioned heels and a good arch support. A laced sports shoe rather than an open sandal is probably best. Avoid old or worn shoes that may not give a good cushion to your heel. Heel
pads and arch supports. You can buy various pads and shoe inserts to cushion the heel and support the arch of your foot. These work best if you put them in your shoes at all times. The aim is to
raise your heel by about 1 cm. If your heel is tender, cut a small hole in the heel pad at the site of the tender spot. This means that the tender part of your heel will not touch anything inside
your shoe. Place the inserts/pads in both shoes, even if you only have pain in one foot. Pain relief. Painkillers such as paracetamol will often ease the pain. Sometimes anti-inflammatory medicines
such as ibuprofen are useful. These are painkillers but also reduce inflammation and may work better than ordinary painkillers. Some people find that rubbing a cream or gel that contains an
anti-inflammatory medicine on to their heel is helpful. An ice pack (such as a bag of frozen peas wrapped in a tea towel) held to your foot for 15-20 minutes may also help to relieve pain. Exercises.
Regular, gentle stretching of your Achilles tendon and plantar fascia may help to ease your symptoms. This is because most people with plantar fasciitis have a slight tightness of their Achilles
tendon. If this is the case, it tends to pull at the back of your heel and has a knock-on effect of keeping your plantar fascia tight. Also, when you are asleep overnight, your plantar fascia tends
to tighten up (which is why it is usually most painful first thing in the morning). The aim of these exercises is to loosen up the tendons and fascia gently above and below your heel. Your doctor may
refer you to a physiotherapist for exercise guidance.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured
fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are
sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if
it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
