Plantar fasciitis is the most common cause of heel pain in runners, eventually affecting 10 percent of the running community. While running, the plantar fascia works with the Achilles tendon to store and return energy. Because of its powerful attachment to the base of the toe, the plantar fascia stabilizes the inner forefoot as forces peak during pushoff. Unlike bone spurs and stress fractures of the heel, plantar fasciitis tends to produce pain during the pushoff phase while running, not during initial contact. A simple way to tell if you have plantar fasciitis versus a heel spur/stress fracture is to walk on your toes: heel spurs and heel stress fractures feel better while you walk on your toes, while plantar fasciitis typically produces more discomfort when you shift your weight onto your toes.
Currently no single factor has been reliably identified as contributing to the development of plantar fasciitis. The two risk factors with the most support from current research. Decreased ankle dorsiflexion. Increased Body Mass Index (BMI) in non-athletic populations. These factors are related in that both lead to increased strain on the arch, both lead to increased compression on the heel. When dorsiflexion range of motion (ankle flexibility) is lacking, the body compensates by increasing movement of the arch. In this way, decreased ankle dorsiflexion influences pronation and places strain on the underside of the foot. Similarly, having a high BMI causes strain because it places a load on the foot that may be in excess of what the foot can support. As mentioned earlier, overpronation is thought to be a contributing factor, but studies on this have so far produced mixed results. The second way these factors relate to each other is in the way people stand. A lack of ankle flexibility and a high BMI can both cause increased pressure on the heel in standing. Keeping weight on the heels causes compression under the heel. But it also means the muscles and ligaments in the arch are not being used to balance your body weight. Lack of use, I suspect, is a greater danger than overuse. Looking beyond these potential contributors to heel pain though, there is one major factor that overshadows them all-the way footwear alters the normal function of the foot.
A sharp pain in the center of your heel will most likely be one of the biggest symptoms of plantar fasciitis. A classic sign of plantar fasciitis is when the pain is worst during the first steps you take in the morning.
To diagnose plantar fasciitis, your doctor will physically examine your foot by testing your reflexes, balance, coordination, muscle strength, and muscle tone. Your doctor may also advise a magnetic resonance imaging (MRI) or X-ray to rule out other others sources of your pain, such as a pinched nerve, stress fracture, or bone spur.
Non Surgical Treatment
Anti-inflammatory agents used in the treatment of plantar fasciitis include ice, NSAIDs, iontophoresis and cortisone injections. Ice is applied in the treatment of plantar fasciitis by ice massage, ice bath or in an ice pack. For ice massage, the patient freezes water in a small paper or foam cup, then rubs the ice over the painful heel using a circular motion and moderate pressure for five to 10 minutes. To use an ice bath, a shallow pan is filled with water and ice, and the heel is allowed to soak for 10 to 15 minutes. Patients should use neoprene toe covers or keep the toes out of the ice water to prevent injuries associated with exposure to the cold. Crushed ice in a plastic bag wrapped in a towel makes the best ice pack, because it can be molded to the foot and increase the contact area. A good alternative is the use of a bag of prepackaged frozen corn wrapped in a towel. Ice packs are usually used for 15 to 20 minutes. Icing is usually done after completing exercise, stretching, strengthening and after a day’s work.
Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or extracorporeal shock wave treatments.
