Heel pain is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as a stress
fracture, tendonitis, arthritis, nerve irritation, or, rarely, a cyst. Because there are several potential causes, it is important to have heel pain properly diagnosed. A foot and ankle surgeon is
able to distinguish between all the possibilities and determine the underlying source of your heel pain. Plantar fasciitis is an inflammation of the band of tissue (the plantar fascia) that extends
from the heel to the toes. In this condition, the fascia first becomes irritated and then inflamed, resulting in heel pain.
Plantar fasciitis is common in sports which involve running, dancing or jumping. Runners who overpronate where their feet roll in or flatten too much are particularly at risk the plantar fascia is
over stretched as the foot flattens. A common factor is tight calf muscles which lead to a prolonged or high velocity pronation or rolling in of the foot. This in turn produces repetitive
over-stretching of the plantar fascia leading to possible inflammation and thickening of the tendon. As the fascia thickens it looses flexibility and strength. Other causes include either a low arch
called pes planus or a very high arched foot known as pes cavus. Assessing the foot for plantar fasciitisExcessive walking in footwear which does not provide adequate arch support has been
attributed. Footwear for plantar fasciitis should be flat, lace-up and with good arch support and cushioning. Overweight individuals are more at risk of developing plantar fasciitis due to the excess
weight impacting on the foot.
The heel pain characteristic of plantar fasciitis is usually felt on the bottom of the heel and is most intense with the first steps of the day. Individuals with plantar fasciitis often have
difficulty with dorsiflexion of the foot, an action in which the foot is brought toward the shin. This difficulty is usually due to tightness of the calf muscle or Achilles tendon, the latter of
which is connected to the back of the plantar fascia. Most cases of plantar fasciitis resolve on their own with time and respond well to conservative methods of treatment.
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
Many types of treatment have been used to combat plantar fasciitis, including injections, anti-inflammatory medications, orthotics, taping, manipulation, night splinting, and instrument-assisted
soft-tissue manipulation (IASTM). IASTM begins with heat, followed by stretching. Stretching may be enhanced by applying ice to the plantar fascia. These stretches should be performed several times
per day, with the calf in the stretched position. IASTM uses stainless-steel instruments to effectively access small areas of the foot. IASTM is believed to cause a secondary trauma to injured soft
tissues as part of the healing process. Therapeutic modalities such as low-level laser, ultrasound, and electrical muscular stimulation may be effective in the reduction of pain and inflammation. Low
Dye strapping or taping of the foot is an essential part of successful treatment of plantar fasciitis. Extracorporeal shock-wave therapy (ESWT) was introduced with great promise at one time. Recent
studies have reported less favorable results. Some report no effect. Previous local steroid injection may actually have a negative effect on results from ESWT.
Surgery may be considered in very difficult cases. Surgery is usually only advised if your pain has not eased after 12 months despite other treatments. The operation involves separating your plantar
fascia from where it connects to the bone; this is called a plantar fascia release. It may also involve removal of a spur on the calcaneum if one is present. Surgery is not always successful. It can
cause complications in some people so it should be considered as a last resort. Complications may include infection, increased pain, injury to nearby nerves, or rupture of the plantar fascia.
More than with most sports injuries, a little bit of prevention can go a long way toward keeping you free from plantar fasciitis. Here are some tips to follow. Wear supportive shoes that fit you
well. When your shoes start to show wear and can no longer give your feet the support they need, it's time to get a new pair. Runners should stop using their old shoes after about 500 miles of use.
Have a trained professional at a specialty running store help you find the right pair for your foot type, and then keep your shoes tied and snug when you wear them. Stay in good shape. By keeping
your weight in check, you'll reduce the amount of stress on your feet. Stretch your calves and feet before you exercise or play a sport. Ask an athletic trainer or sports medicine specialist to show
you some dynamic stretching exercises. Start any new activity or exercise slowly and increase the duration and intensity of the activity gradually. Don't go out and try to run 10 miles the first time
you go for a jog. Build up to that level of exercise gradually. Talk to your doctor about getting heel pads, custom shoe inserts, or orthotics to put in your shoes. Foot supports can help cushion
your feet and distribute your weight more evenly. This is especially true for people with high arches or flat feet. Your doctor will be able to tell you if shoe inserts and supports might lower your
chances of heel injury.
