Heel pain is most commonly caused by plantar fasciitis, which is the swelling of the tissue that connects the heel bone to the toes at the bottom part of the foot, also known as the plantar fascia. Plantar fasciitis is often described as sharp pain in the middle of the heel, which is typically worse after periods of rest when fascia contracts. The pain usually becomes more bearable as the muscles loosen up during the low-impact walking, but can return even worse after extended periods of walking or standing. The plantar fascia serves as a shock absorber and supports the foot’s arch. Too much tension on the plantar fascia can cause inflammation and swelling. Fortunately in most cases, plantar fasciitis treatment is fairly conservative. Plantar fasciitis exercises, medications and orthotics are usually all that’s needed to manage the pain. Most severe cases may require surgery.
It usually starts following an increase in activity levels. Increase in weight. Standing for long periods. Poor footwear. Tight muscle groups. Abnormal pressure on the plantar Fascia can be caused by any of the above. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area that then causes the pain on standing.
Most patients with plantar fasciitis describe a sharp or stabbing pain on the bottom of the heel that is most severe when they first get up in the morning or after a period of resting. Some may feel like the heel is bruised while others may describe tightness or even a pulling sensation on the heel or arch.
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
Your GP or podiatrist may advise you to change your footwear. You should avoid wearing flat-soled shoes, because they will not provide your heel with support and could make your heel pain worse. Ideally, you should wear shoes that cushion your heels and provide a good level of support to the arches of your feet. For women wearing high heels, and for men wearing heeled boots or brogues, can provide short- to medium-term pain relief, as they help reduce pressure on the heels. However, these types of shoes may not be suitable in the long term, because they can lead to further episodes of heel pain. Your GP or podiatrist can advise on footwear. Orthoses are insoles that fit inside your shoe to support your foot and help your heel recover. You can buy orthoses off-the-shelf from sports shops and larger pharmacies. Alternatively, your podiatrist should be able to recommend a supplier. If your pain does not respond to treatment and keeps recurring, or if you have an abnormal foot shape or structure, custom-made orthoses are available. These are specifically made to fit the shape of your feet. However, there is currently no evidence to suggest that custom-made orthoses are more effective than those bought off-the-shelf. An alternative to using orthoses is to have your heel strapped with sports strapping (zinc oxide) tape, which helps relieve pressure on your heel. Your GP or podiatrist can teach you how to apply the tape yourself. In some cases, night splints can also be useful. Most people sleep with their toes pointing down, which means tissue inside the heel is squeezed together. Night splints, which look like boots, are designed to keep your toes and feet pointing up while you are asleep. This will stretch both your Achilles tendon and your plantar fascia, which should help speed up your recovery time. Night splints are usually only available from specialist shops and online retailers. Again, your podiatrist should be able to recommend a supplier. If treatment hasn't helped relieve your painful symptoms, your GP may recommend corticosteroid injections. Corticosteroids are a type of medication that have a powerful anti-inflammatory effect. They have to be used sparingly because overuse can cause serious side effects, such as weight gain and high blood pressure (hypertension). As a result, it is usually recommended that no more than three corticosteroid injections are given within a year in any part of the body. Before having a corticosteroid injection, a local anaesthetic may be used to numb your foot so you don't feel any pain.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
You can help to prevent plantar fasciitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch and cushion the heel. In people who are prone to episodes of plantar fasciitis, exercises that stretch the heel cord (known as the Achilles tendon) and the plantar fascia may help to prevent plantar fasciitis from returning. Ice massage also can be used on the bottom of the foot after stressful athletic activities. It is possible that strict control of blood sugar will prevent plantar fasciitis in people with diabetes, although this has not been proven.
