What Triggers Plantar Fasciitis To Flare Up

Overview

Plantar fasciitis is thickening of the plantar fascia, a band of tissue running underneath the sole of the foot. The thickening can be due to recent damage or injury, or can be because of an accumulation of smaller injuries over the years. Plantar fasciitis can be painful.




Causes

Plantar Fasciitis is caused by abnormal pronation of the foot. Contributing factors are obesity, weight gain, jobs that require a lot of walking or standing on hard surfaces, badly worn shoes with little support, and also inactivity. As a result of over-pronation, with every step the Plantar Fascia (band of tissue under the foot) is being stretched, resulting in inflammation, irritation and pain at the attachment of the fascia into the heel bone. In some cases the pain is felt under the foot, in the arch. Continuous pulling of the fascia at the heel bone, eventually may lead to the development of bony growth on the heel. This is called a heel spur. When you’re at rest, such as while sleeping, the Plantar Fascia tightens and shortens. When body weight is rapidly applied to the foot, the Fascia must stretch and quickly lengthen, causing micro-tears in the Fascia. As a result, the foot pain is more severe with your first steps in the morning, or after sitting for a long period. Plantar Fasciitis is more likely to happen if you suffer from over-pronation (flattening of the arch), you stand or walk on hard surfaces, for long periods, you are overweight or pregnant, you have tight calf muscles.




Symptoms

The symptoms of plantar fasciitis are pain on the bottom of the heel, pain in the arch of the foot, pain that is usually worse upon arising, pain that increases over a period of months. People with plantar fasciitis often describe the pain as worse when they get up in the morning or after they’ve been sitting for long periods of time. After a few minutes of walking the pain decreases, because walking stretches the fascia. For some people the pain subsides but returns after spending long periods of time on their feet.




Diagnosis

Diagnosis of plantar fasciitis is based on a medical history, the nature of symptoms, and the presence of localised tenderness in the heel. X-rays may be recommended to rule out other causes for the symptoms, such as bone fracture and to check for evidence of heel spurs. Blood tests may also be recommended.




Non Surgical Treatment

The initial treatment of plantar fasciitis focuses on reducing pain and inflammation. Resting the affected foot is the most important aspect of this treatment. Other initial treatment may include, aplying ice to the sole of the foot, Anti-inflammatory medications. Gentle stretching of the plantar fascia and Achilles tendon. Physiotherapy. Taping the foot and ankle to provide adequate support and alignment, Wearing supportive footwear with shock-absorbing soles or inserts. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Brufen) and diclofenac (Voltaren) are often used to treat plantar fasciitis. It is unclear whether NSAIDs assist in the healing process but they are useful for controlling pain during treatment. If the condition does not respond to initial treatment, a corticosteroid therapy may be recommended. This involves the injection of corticosteroid medication such as hydrocortisone (Solu-Cortef) directly into the affected area in order to treat the inflammation and thus relieve the pain. Night splints to prevent the plantar fascia tightening during sleep may also be recommended at this stage.






Surgical Treatment

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.




Prevention

Maintain a healthy weight. This minimizes the stress on your plantar fascia. Choose supportive shoes. Avoid high heels. Buy shoes with a low to moderate heel, good arch support and shock absorbency. Don't go barefoot, especially on hard surfaces. Don't wear worn-out athletic shoes. Replace your old athletic shoes before they stop supporting and cushioning your feet. If you're a runner, buy new shoes after about 500 miles of use. Change your sport. Try a low-impact sport, such as swimming or bicycling, instead of walking or jogging. Apply ice. Hold a cloth-covered ice pack over the area of pain for 15 to 20 minutes three or four times a day or after activity. Or try ice massage. Freeze a water-filled paper cup and roll it over the site of discomfort for about five to seven minutes. Regular ice massage can help reduce pain and inflammation. Stretch your arches. Simple home exercises can stretch your plantar fascia, Achilles tendon and calf muscles.
