Foot pain affects nearly all people at one time or another. It can also lead to other musculoskeletal problems such as ankle, knee and back pain (Hill et al., 2008). This pain negatively affects one’s quality of life and ability to enjoy workouts and/or maintain a regular program of exercise. One of the most common sources of foot pain is plantar fasciitis, a condition where the connective tissue on the underside of the foot becomes irritated and painful as a result of an injury, overuse or misuse. The plantar fascia is a system of connective tissue that runs from your heel to just behind your toes. During weightbearing activities, such as walking or running, your body weight is transferred onto your foot from your heel to your toes (which results in your toes moving away from your heel). This spreading out of the foot places tension on the plantar fascia because it connects those two parts. If the tension on this structure is too great or is not dispersed evenly, the plantar fascia can develop microtears and become irritated and painful, resulting in a condition called plantar fasciitis.
Because the plantar fascia supports your foot and gets used every time you take a step, it has to absorb a large amount of stress and weight. If too much pressure is put on the plantar fascia, the fibers can become damaged or start to tear. The body responds by causing inflammation in the affected area. This is what causes the pain and stiffness of plantar fasciitis. Things that can increase the risk of plantar fasciitis include tight calf muscles. Tight calves make it harder to flex your foot, and this puts more stress on the plantar fascia. Weight. Carrying a few extra pounds puts added pressure on your feet every time you take a step. Activities that put a lot of stress on the feet. This includes things like running, hiking, dancing, and aerobics. Bad shoes. Footwear that doesn't give your foot the support it needs increases your risk of plantar fasciitis. You'll want to ditch any shoes that have thin soles or inadequate arch support, or ones that don't fit your feet properly. Routinely wearing high heels can also cause your Achilles tendon to contract over time, making it harder to flex your foot. Jobs that involve a lot of standing or walking on hard surfaces. Jobs that keep you on your feet all day, like waiting tables or working in a store, can cause damage to your plantar fascia. High arches, flat feet, or other foot problems. The shape of your foot can affect the way your weight is distributed on your feet when you stand. If weight distribution is a bit off, it can add to a person's risk of plantar fasciitis. How someone walks can increase the stress on certain parts of the foot too.
When a patient has plantar fasciitis, the connective tissue that forms the arch of the foot becomes inflamed (tendonitis) and degenerative (tendinosis)--these abnormalities cause plantar fasciitis and can make normal activities quite painful. Symptoms of plantar fasciitis are typically worsened early in the morning after sleep. At that time, the arch tissue is tight and simple movements stretch the contracted tissue. As you begin to loosen the foot, the pain usually subsides, but often returns with prolonged standing or walking.
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
You may experience concern in reading about treatment options for this condition that involve taking medications, having injections or undergoing surgery. While these remedies may be necessary in some cases, there are natural, non-invasive, affordable methods for treating and healing Plantar Fasciitis. A simple, three-step approach may be all you need to experience immediate or rapid symptom relief. Step 1) Give Your Feet A Rest. When a ligament is stressed and inflamed, it is absolutely essential to take pressure off it and let it rest. Adjust your daily habits to spend some time each day off your feet. Step 2) Ice Brings Cooling Relief. Apply an ice bag or cold pack to your heel for twenty minutes, twice a day. This will numb soreness and help control inflammation. Step 3) Gain Support From Orthotics. Orthotics are devices designed to modify body motions or lessen pressure on areas of the body. In the case of foot orthotics, these products may include splints, wraps and shoe inserts.
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.
