What Is Heel Discomfort

Plantar Fascitis

Overview

Plantar Fasciitis is actually, in most cases, plantar fasciosis but it’s a bit like pen/biro or hoover/vacuum. The term ‘-itis‘ means ‘inflammation’. This is a term we use for this problem in the early stages of damage because it usually is quite literally an inflammation of part of the plantar fascia. So, what is commonly known as ‘plantar fasciitis’ is really ‘plantar fasciosis’ - a degradation or degeneration of the collagen fibres because of prolonged (most of your adult life) unsustainable stress being applied to the fascia. So, we call it plantar fasciitis but it usually hasn’t been an ‘-itis‘ for years and that is why in many cases anti-inflammatory drugs do not help ease the pain of walking. This is also why most sufferers experience pain first thing in the morning. If inflammation was the source of discomfort then why would it hurt after a nights rest and the good old drugs pumping through your system.




Causes

Excessive stretching of the plantar fascia can result in microtrauma of this structure either along its course or where it inserts onto the medial calcaneal tuberosity. This microtrauma, if repetitive, can result in chronic degeneration of the plantar fascia fibers. The loading of the degenerative and healing tissue at the plantar fascia may cause significant plantar pain, particularly with the first few steps after sleep or other periods of inactivity. The term fasciitis may, in fact, be something of a misnomer, because the disease is actually a degenerative process that occurs with or without inflammatory changes, which may include fibroblastic proliferation. This has been proven from biopsies of fascia from people undergoing surgery for plantar fascia release.




Symptoms

The pain associated with plantar fasciitis is typically gradual in onset and is usually located over the inner or medial aspect of the heel. Occasionally, the pain will be sudden in onset, occurring after missing a step or after jumping from a height. The pain is commonly most severe upon arising from bed in the morning, or after periods of inactivity during the day. Thus, it causes what is known as "first-step pain." The degree of discomfort can sometimes lessen with activity during the course of the day or after "warming-up", but can become worse if prolonged or vigorous activity is undertaken. The pain is also often noted to be more severe in bare feet or in shoes with minimal or no padding at the sole.




Diagnosis

X-rays are a commonly used diagnostic imaging technique to rule out the possibility of a bone spur as a cause of your heel pain. A bone spur, if it is present in this location, is probably not the cause of your pain, but it is evidence that your plantar fascia has been exerting excessive force on your heel bone. X-ray images can also help determine if you have arthritis or whether other, more rare problems, stress fractures, bone tumors-are contributing to your heel pain.




Non Surgical Treatment

Rest until the pain resolves and you are feeling better. For most people with plantar fasciitis it is very difficult to rest as daily routine demands using their feet during the day for work or other activities. By using the painful foot you keep on hurting the plantar fascia, harming the foot and increasing inflammation. Rest as much as you can, reduce unnecessary activities and additional stress on the fascia. Cold therapy like applying ice to the bottom of your foot helps reduce pain and inflammation. Cold therapy can be used all the time until symptoms have resolved. Some patients prefer to roll their foot over an iced cold drink can or bottle taken out of the freezer. Physical therapy Exercises are good plantar fasciitis treatment. Stretching and other physical therapy measures may be used to provide relief. Stretching the plantar fascia is reported in scientific studies to be a very effective treatment technique. Gait analysis will determine if you overpronate or oversupinate. An expert may perform a test of the way you stand and walk to see if you step in a way that puts more stress on the plantar fascia. You can try to change the way you walk and stand according to the experts recommendation as part of your treatment. Exercise the foot muscles to make the muscles stronger. One good exercise is grabbing and lifting up a towel or marbles using your toes. You can do the same exercise without a towel as though you are grasping something with the toes of each foot. Another good exercise is walking as tall as you can on your toes and on the balls of your feet. Stretching the plantar fascia and the calf muscles several times a day is an important part of the treatment and prevention. There are many stretching exercises for the plantar fascia and the calf muscles that you can find. Long term treatment should not focus in reduction of pain and inflammation alone. This is a passive short term relief treatment. Stretching exercises results are longer and more flexible foot movement which can prevent another fascia injury. Plantar fasciitis taping technique can assist the foot getting rest and help it from getting injured again. Athletic tape is applied in strips on the skin on the bottom of the foot supporting the plantar fascia. The tape restricts the movement of the foot so the fascia can not be injured again. Taping supports the foot by putting the tired foot muscles and tendons in a physiologically more relaxed position. A night splint is worn during sleep. It holds the calf muscles and plantar fascia in a stretched position. Night splint treatment lets the fascia heal in a stretched position so it will not get bruised again when waking up and stretching it again while walking. Orthotics or inserts that your doctor may prescribe or custom made arch supports (orthotics) plantar fascia orthotic. help to distribute the pressure on your feet more evenly. Arch Support gives a little raise to the arch assisting the plantar fascia. There are also over-the-counter inserts that are used for arch support and heel cushioning. Heel cups and cradles provide extra comfort and cushion the heel. They reduce shock placed on the foot during everyday activities like Shock absorbers. Anti-inflammatory or Pain medication that a clinician may recommend can be a plantar fasciitis treatment. Non-steroidal anti-inflammatory drugs such as ibuprofen can reduce swelling and relieve pain. However, these medications may have many side effects and it is important to consider the potential risks and benefits. These medications may relieve the pain and inflammation but will not cure the fascia. Lose weight as much as you can. Extra weight puts more stress on your plantar fascia. Platelet Rich Plasma or PRP therapy, is a procedure which involves an injection of special plasma, made out of the patients own blood, to the injured area. Platelets are special blood components that have a major role in the body ability to heal itself. Blood is taken from the patient and separated into its components. The platelet rich part of the blood is than taken and injected into the injured area - in our case to the bottom of the foot. The special plasma helps the foot recovery process. The procedure is actually maximizing the body's natural healing response of the treated area. Extracorporeal shock wave therapy is a procedure which sound waves are targeted at the area of heel pain to encourage healing. It is mostly used for chronic plantar fasciitis which does not respond to conservative treatments. This procedure has many possible side effects like bruising, swelling, pain or numbness and has not proved to be consistently effective. Corticosteroid injection (or cortisone shots) into the painful area may provide relief in severe cases. This kind of medication is very efficient in inflammation reduction. Corticosteroid injections usually provide short-term relief from plantar fasciitis pain. Symptom relief from the corticosteroid injection lasts for 3 to 6 weeks, but the effect often deteriorates and symptoms return. Botox Injections (botulinum toxin) are used to relieve the pain of plantar fasciitis, assist foot function recovery and the ability to walk better. Although the use of Botox injections as heel pain treatment is relatively new, there are a number of medical studies that show significant good results.

Feet Pain




Surgical Treatment

If treatment hasn't worked and you still have painful symptoms after a year, your GP may refer you to either an orthopaedic surgeon, a surgeon who specialises in surgery that involves bones, muscles and joints, a podiatric surgeon, a podiatrist who specialises in foot surgery. Surgery is sometimes recommended for professional athletes and other sportspeople whose heel pain is adversely affecting their career. Plantar release surgery. Plantar release surgery is the most widely used type of surgery for heel pain. The surgeon will cut the fascia to release it from your heel bone and reduce the tension in your plantar fascia. This should reduce any inflammation and relieve your painful symptoms. Surgery can be performed either as, open surgery, where the section of the plantar fascia is released by making a cut into your heel, endoscopic or minimal incision surgery - where a smaller incision is made and special instruments are inserted through the incision to gain access to the plantar fascia. Endoscopic or minimal incision surgery has a quicker recovery time, so you will be able to walk normally much sooner (almost immediately), compared with two to three weeks for open surgery. A disadvantage of endoscopic surgery is that it requires both a specially trained surgical team and specialised equipment, so you may have to wait longer for treatment than if you were to choose open surgery. Endoscopic surgery also carries a higher risk of damaging nearby nerves, which could result in symptoms such as numbness, tingling or some loss of movement in your foot. As with all surgery, plantar release carries the risk of causing complications such as infection, nerve damage and a worsening of your symptoms after surgery (although this is rare). You should discuss the advantages and disadvantages of both techniques with your surgical team. Extracorporeal shockwave therapy (EST) is a fairly new type of non-invasive treatment. Non-invasive means it does not involve making cuts into your body. EST involves using a device to deliver high-energy soundwaves into your heel. The soundwaves can sometimes cause pain, so a local anaesthetic may be used to numb your heel. It is claimed that EST works in two ways. It is thought to, have a "numbing" effect on the nerves that transmit pain signals to your brain, help stimulate and speed up the healing process. However, these claims have not yet been definitively proven. The National Institute for Health and Care Excellence (NICE) has issued guidance about the use of EST for treating plantar fasciitis. NICE states there are no concerns over the safety of EST, but there are uncertainties about how effective the procedure is for treating heel pain. Some studies have reported that EST is more effective than surgery and other non-surgical treatments, while other studies found the procedure to be no better than a placebo (sham treatment).




Stretching Exercises

The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free.
