Plantar fasciitis is that pain in the bottom of your foot usually in the heel. That pain hurts especially with the first few steps in the morning as you get out of bed. This strange name comes from: “Plantar” means something that belongs to the foot, “fascia” means a band or ligament or a connective tissue, and “itis” means inflammation. You can see in the picture the plantar fascia band as it runs along the foot. This band connects your heel bone to the toes.
A variety of causes exist for plantar fasciitis. Some of the most common causes include excessive weight load on the foot due to obesity or prolonged standing, mechanical imbalances of the foot, osteoarthritis and rheumatoid arthritis, sudden increase in body weight (e.g., pregnancy), sudden increase in walking or running, tight calf muscles is a very common cause of the disorder, wearing shoes with poor support, including flip-flops. Another cause of pain is the shortening of the plantar fascia overnight due to the ankle bending, causing the toes to point towards the ground. The plantar fascia stretches in the morning when you stand. The act of lengthening it causes a great deal of pain. However, this is not limited to an overnight occurrence, it can happen any time the foot is flexed (i.e., pointed) for extended periods of time. For example, driving in the car for long periods can cause fasciitis in the right foot, which steps on the accelerator.
Patients with plantar fasciitis typically experience pain underneath the heel and along the inner sole of the foot. In less severe cases, patients may only experience an ache or stiffness in the plantar fascia or heel that increases with rest (typically at night or first thing in the morning) following activities which place stress on the plantar fascia. These activities typically include standing, walking or running excessively (especially up hills, on uneven surfaces or in poor footwear such as thongs), jumping, hopping and general weight bearing activity. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with this condition may also experience swelling, tenderness on firmly touching the plantar fascia (often on a specific spot on the inner aspect of the heel) and sometimes pain on performing a plantar fascia stretch.
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
Management options are usually conservative. Local injection of steroids, local anaesthetic may be useful to manage symptoms. Ultrasound-guided steroid injection has been shown to be effective in short-term (four-week) pain relief and reduced thickness of the plantar fascia at three months. A posterior tibial nerve block can be performed prior for a less painful plantar fascia injection. Specific plantar fascia stretching exercises performed daily have been shown to reduce short-term (8 weeks) and long-term (two years) pain. Other supportive measures include weight reduction in obese patients, rest, non-steroidal anti-inflammatory drugs (NSAIDs) and reduction of weight-bearing pressure (soft rubber heel pad, molded orthosis, or heel cup or soft-soled shoes).
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
Calf stretch. Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch. Plantar fascia stretch. This stretch is performed in the seated position. Cross your affected foot over the knee of your other leg. Grasp the toes of your painful foot and slowly pull them toward you in a controlled fashion. If it is difficult to reach your foot, wrap a towel around your big toe to help pull your toes toward you. Place your other hand along the plantar fascia. The fascia should feel like a tight band along the bottom of your foot when stretched. Hold the stretch for 10 seconds. Repeat it 20 times for each foot. This exercise is best done in the morning before standing or walking.
