Everything You Need To Know About Heel Pain

Overview

Heel Discomfort

Heel Pain may develop when you pound your feet on hard surfaces playing sports or wear shoes that irritate sensitive tissues. A sore heel will usually get better on its own if you give it enough rest. Unfortunately, many people try to ignore the early signs of heel pain and keep on doing the activities that caused it and this can lead to chronic pain. Conditions that cause heel pain generally fall into two main categories: pain beneath the heel and pain behind the heel. Pain beneath the Heel. If it hurts under your heel, you may have one or more conditions that cause inflammation of the tissues on the bottom of your foot. Stone bruise. By stepping on a hard object, you can bruise the fat pad on the bottom side of your heel. It may or may not look discoloured. With rest, the pain subsides gradually.

Causes

A sharp stabbing pain, like a nail going into the bottom of the heel when first stepping on the foot after getting out of bed or after sitting for period of time, is the most common description for plantar fasciitis or heel spur syndrome. Typically the pain eases off as the day goes on but it may not go away completely. A thick ligament that attaches to the bottom of the heel and runs the length of the foot to the toes can become inflamed and swollen at the attachment site. This tends to be an overuse type of injury where poor foot structure is involved; also, wearing of shoe gear that lacks adequate support (ie: worn out shoes, boots and flip-flops) and prolonged standing or walking are often implicated. A throbbing pain that gets worse as the day goes on and can be worse at night when laying in bed is most often associated with an irritated or entrapped nerve on the inside of the ankle or heel. This is similar to carpel tunnel syndrome in the wrist and hand. Approximately 7 / 10 patients with heel pain have a component of nerve entrapment as the cause of their heel pain. This is also one of the most common causes of chronic heel pain because it is often missed as a diagnosis. When nerve entrapment is considered to be a cause, painless neurosensory testing is performed with the Pressure Specified Sensory Device? (PSSD) at The Foot & Ankle Center, PC to determine the extent of compression. A less common cause of heel pain but a stress fracture is often considered in athletes, such as long distance runners, who have heel pain. Posterior Heel Pain (Retrocalcaneal) This is pain in the back of the heel that flares up when first starting an activity. It is often associated with a large bump that can be irritated by shoes. The Achilles tendon attaches to the back of the heel and, like on the bottom, this attachment site can often become inflamed; a spur may or may not be present. Another painful area is a sac of fluid (bursa) that sits between the tendon and bone to act as a cushion for the tendon. This bursa can become inflamed often leading to significant pain called retrocalcaneal bursitis.

Symptoms

Depending on the specific form of heel pain, symptoms may vary. Pain stemming from plantar fasciitis or heel spurs is particularly acute following periods of rest, whether it is after getting out of bed in the morning, or getting up after a long period of sitting. In many cases, pain subsides during activity as injured tissue adjusts to damage, but can return again with prolonged activity or when excessive pressure is applied to the affected area. Extended periods of activity and/or strain of the foot can increase pain and inflammation in the foot. In addition to pain, heel conditions can also generate swelling, bruising, and redness. The foot may also be hot to the touch, experience tingling, or numbness depending on the condition.

Diagnosis

Your doctor will perform a physical exam and ask questions about your medical history and symptoms, such as have you had this type of heel pain before? When did your pain begin? Do you have pain upon your first steps in the morning or after your first steps after rest? Is the pain dull and aching or sharp and stabbing? Is it worse after exercise? Is it worse when standing? Did you fall or twist your ankle recently? Are you a runner? If so, how far and how often do you run? Do you walk or stand for long periods of time? What kind of shoes do you wear? Do you have any other symptoms? Your doctor may order a foot x-ray. You may need to see a physical therapist to learn exercises to stretch and strengthen your foot. Your doctor may recommend a night splint to help stretch your foot. Surgery may be recommended in some cases.

Non Surgical Treatment

If you still have pain after several weeks, see your foot and ankle surgeon, who may add one or more of these treatment approaches, padding and strapping. Placing pads in the shoe softens the impact of walking. Strapping helps support the foot and reduce strain on the fascia. Orthotic devices. Custom orthotic devices that fit into your shoe help correct the underlying structural abnormalities causing the plantar fasciitis. Injection therapy. In some cases, corticosteroid injections are used to help reduce the inflammation and relieve pain. Removable walking cast. A removable walking cast may be used to keep your foot immobile for a few weeks to allow it to rest and heal. Night splint. Wearing a night splint allows you to maintain an extended stretch of the plantar fascia while sleeping. This may help reduce the morning pain experienced by some patients. Physical therapy. Exercises and other physical therapy measures may be used to help provide relief.

Surgical Treatment

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).

Prevention

Pain Under The Heel

You can help to prevent heel pain by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
