The plantar fascia is a thick band of connective tissue that runs along the underneath of the foot from the heel bone to the toes. At the heel it can also have fascial connections to the achilles tendon. Its job is to maintain the arch of the foot, it acts as a bowstring pulled between the heel and the toes. "Itis" as a suffix indicates inflammation, but with the plantar fascia there is still some controversy over what exactly happens to the tissue when it becomes painful.
Plantar fasciitis symptoms are usually exacerbated via "traction" (or stretching) forces on the plantar fascia. In simple terms, you plantar fascia is repeatedly overstretched. The most common reason for the overstretching are an elongated arch due to either poor foot biomechanics (eg overpronation) or weakness of your foot arch muscles. Compression type plantar fascia injuries have a traumatic history. Landing on a sharp object that bruises your plantar fascia is your most likely truma. The location of plantar fasciitis pain will be further under your arch than under your heel, which is more likely to be a fat pad contusion if a single trauma caused your pain. The compression type plantar fasciitis can confused with a fat pad contusion that is often described as a "stone bruise".
Plantar fasciitis commonly causes a stabbing pain in the heel of the foot, which is worse during the first few steps of the day after awakening. As you continue to walk on the affected foot, the pain gradually lessens. Usually, only one foot is affected, but it can occur in both feet simultaneously.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
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.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
