Pain arises in the centre of the heel and sometimes can spread to the arch region of the foot. Some patients complain of intense Heel Pain when walking the first few steps in the morning and after periods of rest. The most common cause of heel pain is plantar fascitis. The plantar fascia is a broad band of tissue that runs along the bottom of the foot. When this band of tissue is damaged due to biomechanical reasons or inappropriate running shoes then the tissue can become inflamed or even tear at the heel bone. This can be very painful.
Heel pain sometimes results from excessive pronation. Pronation is the normal flexible motion and flattening of the arch of the foot that allows it to adapt to ground surfaces and absorb shock in the normal walking pattern. As you walk, the heel contacts the ground first; the weight shifts first to the outside of the foot, then moves toward the big toe. The arch rises, the foot generally rolls upward and outward, becoming rigid and stable in order to lift the body and move it forward. Excessive pronation-excessive inward motion-can create an abnormal amount of stretching and pulling on the ligaments and tendons attaching to the bottom back of the heel bone. Excessive pronation may also contribute to injury to the hip, knee, and lower back.
The heel can be painful in many different ways, depending on the cause. Plantar fasciitis commonly causes intense heel pain along the bottom of the foot during the first few steps after getting out of bed in the morning. This heel pain often goes away once you start to walk around, but it may return in the late afternoon or evening. Although X-ray evidence suggests that about 10% of the general population has heels spurs, many of these people do not have any symptoms. In others, heel spurs cause pain and tenderness on the undersurface of the heel that worsen over several months. In a child, this condition causes pain and tenderness at the lower back portion of the heel. The affected heel is often sore to the touch but not obviously swollen. Bursitis involving the heel causes pain in the middle of the undersurface of the heel that worsens with prolonged standing and pain at the back of the heel that worsens if you bend your foot up or down. Pump bump, this condition causes a painful enlargement at the back of the heel, especially when wearing shoes that press against the back of the heel. Heel bruises, like bruises elsewhere in the body, may cause pain, mild swelling, soreness and a black-and-blue discoloration of the skin. Achilles tendonitis, this condition causes pain at the back of the heel where the Achilles tendon attaches to the heel. The pain typically becomes worse if you exercise or play sports, and it often is followed by soreness, stiffness and mild swelling. A trapped nerve can cause pain, numbness or tingling almost anywhere at the back, inside or undersurface of the heel. In addition, there are often other symptoms, such as swelling or discoloration - if the trapped nerve was caused by a sprain, fracture or other injury.
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot - this could be a sign of nerve damage in your feet and legs (peripheral neuropathy), your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above - these could be signs of a bone infection, you have stiffness and swelling in your heel - this could be a sign of arthritis. Possible further tests may include, blood tests, X-rays - where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
Non Surgical Treatment
Depending on the underlying cause, treatment can include. Rest from activities that stress the heel (such as running and jumping). Ice packs. Regular foot massage, concentrating on the arch of the foot. Professional strapping. A splint worn at night. Flexibility exercises. Ultrasound therapy. Anti-inflammatory medicine (topical or oral). Checking your posture and walking style, to correct imbalances and gait abnormalities that may contribute to the pain. Shoe inserts (orthoses) to help support the foot. In some cases, surgery may be recommended to treat conditions including neuroma, bursitis and heel spurs.
Although most patients with plantar fasciitis respond to non-surgical treatment, a small percentage of patients may require surgery. If, after several months of non-surgical treatment, you continue to have heel pain, surgery will be considered. Your foot and ankle surgeon will discuss the surgical options with you and determine which approach would be most beneficial for you. No matter what kind of treatment you undergo for plantar fasciitis, the underlying causes that led to this condition may remain. Therefore, you will need to continue with preventive measures. Wearing supportive shoes, stretching, and using custom orthotic devices are the mainstay of long-term treatment for plantar fasciitis.
It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Being overweight can place excess pressure and strain on your feet, particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI, divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI.
