Overview
Heel Pain is often the result of a heel spur, which is a bone growth on the heel bone. Heel spurs are usually located on the underside of the heel bone where it attaches to the plantar fascia, a long band of connective tissue running from the heel to the ball of the foot. This connective tissue holds the arch together and acts as a shock absorber during activity. If the plantar fascia is over-stretched from running, wearing poor-fitting shoes or being overweight, pain can result from the stress and inflammation of the tissue pulling on the bone. Over time, the body builds extra bone in response to this stress resulting in heel spurs.
Causes
he most common cause of heel pain is over pronation, this is when your foot rotates in too much as you walk. You really need to treat the underlying cause of the heel pain as soon as possible to prevent any further damage to the plantar fascia. Excessive load on the foot from obesity is a major cause of plantar fasciitis. Which is why this condition is common in middle aged and over weight adults. A sudden increase in weight, such as pregnancy can also lead to plantar fascitis. A sudden increase in walking or a sporting activity can also be a contributing factor. A classic example of when this condition can develop is when a post man has returned to work after a period away from the job. Tight plantar fascia (this is often caused by tight calf muscles). Excessive flattening of the arch on weight bearing i.e. flat feet. People with flat feet are more at risk of developing this condition. Biomechanical problems (walking abnormalities) is a major cause of plantar fasciitis. Different types of arthritis can also lead to this condition, such as osteoarthritis and rheumatoid arthritis.
Symptoms
Pain typically comes on gradually, with no injury to the affected area. It is frequently triggered by wearing a flat shoe, such as flip-flop sandals. Flat footwear may stretch the plantar fascia to such an extent that the area becomes swollen (inflamed). In most cases, the pain is under the foot, toward the front of the heel. Post-static dyskinesia (pain after rest) symptoms tend to be worse just after getting out of bed in the morning, and after a period of rest during the day. After a bit of activity symptoms often improve a bit. However, they may worsen again toward the end of the day.
Diagnosis
A podiatrist (doctor who specializes in the evaluation and treatment of foot diseases) will carry out a physical examination, and ask pertinent questions about the pain. The doctor will also ask the patient how much walking and standing the patient does, what type of footwear is worn, and details of the his/her medical history. Often this is enough to make a diagnosis. Sometimes further diagnostic tests are needed, such as blood tests and imaging scans.
Non Surgical Treatment
The following steps may help relieve your heel pain. Use crutches to take weight off your feet. Rest as much as possible for at least a week. Apply ice to the painful area. Do this at least twice a day for 10 to 15 minutes, more often in the first couple of days. Take acetaminophen or ibuprofen for pain. Wear proper-fitting shoes. Use a heel cup, felt pads in the heel area, or shoe insert. Wear night splints. Your doctor may recommend other treatments, depending on the cause of your heel 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 or 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 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 or 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.
Prevention
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.
