The function of the heel in walking is to absorb the shock of your foot striking the ground as it is put down and to start springing you forward on the next step. It contains a strong bone (the calcaneum). Under the bone are a large number of small pockets of fat in strong elastic linings, which absorb much of the shock (fat pads). The heel is attached to the front of the foot by a number of strong ligaments which run between the front part of the calcaneum and various other parts of the foot. The strongest ligament is the plantar fascia, which attaches the heel to the toes and helps to balance the various parts of the foot as you walk. It therefore takes a lot of stress as you walk. In some people the plantar fascia becomes painful and inflamed. This usually happens where it is attached to the heel bone, although sometimes it happens in the mid-part of the foot. This condition is called plantar fasciitis.
Long standing inflammation causes the deposition of calcium at the point where the plantar fascia inserts into the heel. This results in the appearance of a sharp thorn like heel spur on x-ray. The heel spur is asymptomatic (not painful), the pain arises from the inflammation of the plantar fascia.
The most common complaint is pain and stiffness in the bottom of the heel. Heel pain may be sharp or dull, and it may develop slowly over time or suddenly after intense activity. The pain is typically worse in the morning, when taking your first steps of the day. After standing or sitting for a while. When climbing stairs.
The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.
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.
At most 95% of heel pain can be treated without surgery. A very low percentage of people really need to have surgery on the heel. It is a biomechanical problem and it?s very imperative that you not only get evaluated, but receive care immediately. Having heel pain is like having a problem with your eyes; as you would get glasses to correct your eyes, you should look into orthotics to correct your foot. Orthotics are sort of like glasses for the feet. They correct and realign the foot to put them into neutral or normal position to really prevent heel pain, and many other foot issues. Whether it be bunions, hammertoes, neuromas, or even ankle instability, a custom orthotic is something worth considering.
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.
