Plantar fasciitis is one of the most common sources of heel pain. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the toes. Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes inflammed it is known as plantar fasciitis.
Factors which may contribute to plantar fasciitis and heel spurs include a sudden increase in daily activities, increase in weight (not usually a problem with runners), or a change of shoes. Dramatic increase in training intensity or duration may cause plantar fasciitis. Shoes that are too flexible in the middle of the arch or shoes that bend before the toe joints will cause an increase in tension in the plantar fascia. Even though you may have run in shoes that are flexible before, now that you have developed plantar fasciitis, make certain that your shoe is stable and does not bend in the midfoot. Check and be certain that your shoes are not excessively worn. Shoes that do not sufficiently control excessive pronation combined with an increase in training can lead to this condition. A change in running style or parameters, such as starting speed work, running on the ball of your foot or sudden increase in hill workouts may lead to problems. All changes should be gradual and not abrupt. Gait changes such as altering your foot strike, switching shoe style, running barefoot or in minimalist shoes should all be made gradually and not abruptly. The "terrible too's" of too much, too soon, too often with too little rest also applies to "too many changes with too little adaptation". Make your changes gradually and allow your muscles, bones, and other body structures to adapt to the alterations you may be attempting.
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.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
More than 90% of patients with plantar fasciitis will improve within 10 months of starting simple treatment methods. Rest. Decreasing or even stopping the activities that make the pain worse is the first step in reducing the pain. You may need to stop athletic activities where your feet pound on hard surfaces (for example, running or step aerobics). Ice. Rolling your foot over a cold water bottle or ice for 20 minutes is effective. This can be done 3 to 4 times a day. Nonsteroidal anti-inflammatory medication. Drugs such as ibuprofen or naproxen reduce pain and inflammation. Using the medication for more than 1 month should be reviewed with your primary care doctor. Exercise. Plantar fasciitis is aggravated by tight muscles in your feet and calves. Stretching your calves and plantar fascia is the most effective way to relieve the pain that comes with this condition. Cortisone injections. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to a flat foot and chronic pain. Soft heel pads can provide extra support. Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful. Night splints. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone. Physical therapy. Your doctor may suggest that you work with a physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia. Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged plantar fascia tissue. ESWT has not shown consistent results and, therefore, is not commonly performed. ESWT is noninvasive-it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
Make sure you wear appropriate supportive shoes. Don't over-train in sports. Make sure you warm up, cool down and undertake an exercise regime that helps maintain flexibility. Manage your weight, obesity is a factor in causing plantar fasciitis. Avoid walking and running on hard surfaces if you are prone to pain. You should follow the recognized management protocol - RICED-rest, ice, compression, elevation and diagnosis. Rest, keep off the injured ankle as much as possible. Ice, applied for 20 minutes at a time every hour as long as swelling persists. Compression, support the ankle and foot with a firmly (not tightly) wrapped elastic bandage. Elevation, keep foot above heart level to minimize bruising and swelling. Diagnosis, Consult a medical professional (such as a Podiatrist or doctor) especially if you are worried about the injury, or if the pain or swelling gets worse. If the pain or swelling has not gone down significantly within 48 hours, also seek treatment. An accurate diagnosis is essential for proper rehabilitation of moderate to severe injuries.
