Heel pain is the most common musculoskeletal complaint of patients presenting to podiatric practitioners throughout the country. It is well-recognized that subcalcaneal pain syndrome, commonly attributed to plantar fascitis, is a disease entity that is increasing in its incidence, owing partly to the fact that it has a predilection for people between the age of 40 and 60, the largest age segment in our population.
Plantar Fasciitis is simply caused by overstretching of the plantar fascia ligament under the foot. So why is the ligament being overstretched? There are different factors, over-use, too much sports, running, walking or standing for long periods (e.g. because of your job) weight gain, our feet are designed to carry a ‘normal’ weight. Any excess weight places great pressure on the bones, nerves, muscles and ligaments in the feet, which sooner or later will have consequences. Even pregnancy (in the last 10 weeks) can cause foot problems! age, as we get older ligaments become tighter & shorter and msucles become weaker; the ideal circumstances for foot problems, unsupportive footwear, ‘floppy’ shoes with no support as well as thongs affect our walking pattern, walking barefoot, especially on hard surfaces like concrete or tiles, low arch and flat feet or over-pronation. An important contributing factor to Plantar Fasciitis is ‘excess pronation’ (or over-pronation). This is a condition whereby the feet roll over, the arches collapse and the foot elongates. This unnatural elongation puts excess strain on the ligaments, muscles and nerves in the foot. When the foot is not properly aligned, the bones unlock and cause the foot to roll inward. With every step taken your foot pronates and elongates, stretching the plantar fascia and causing inflammation and pain at the attachment of the plantar fascia into the heel bone. Re-alignment of the foot should therefore an important part of the treament regime.
The major complaint of those with plantar fasciitis is pain and stiffness in the bottom of the heel. This develops gradually over time. It usually affects just one foot, but can affect both feet. Some people describe the pain as dull, while others experience a sharp pain, and some feel a burning or ache on the bottom of the foot extending outward from the heel. The pain is usually worse in the morning when you take your first steps out of bed, or if you’ve been sitting or lying down for a while. Climbing stairs can be very difficult due to the heel stiffness. After prolonged activity, the pain can flare-up due to increased inflammation. Pain is not usually felt during the activity, but rather just after stopping.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
Treatment for heel pain usually involves using a combination of techniques, such as stretches and painkillers, to relieve pain and speed up recovery. Most cases of heel pain get better within 12 months. Surgery may be recommended as a last resort if your symptoms don’t improve after this time. Only 1 in 20 people with heel pain will need surgery. Whenever possible, rest the affected foot by not walking long distances and standing for long periods. However, you should regularly stretch your feet and calves using exercises such as those described below. Pain relief. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can be used to help relieve pain. Some people also find applying an ice pack to the affected heel for 5-10 minutes can help relieve pain and inflammation. However, do not apply an ice pack directly to your skin. Instead, wrap it in a towel. If you do not have an ice pack, you can use a packet of frozen vegetables.
Surgery is not a common treatment for this condition. Approximately 5% of people with plantar fasciitis require surgery if non-surgical methods do not help to relieve pain within a year. The surgical procedure involves making an incision in the plantar fascia in order to decrease the tension of the ligament. Potential risks of this surgical procedure include irritation of the nerves around the heel, continued plantar fasciitis, heel or foot pain, infection, flattening of the arch, problems relating to the anesthetic.
