The plantar fascia is a band of connective tissue on the bottom of the foot that helps form the arch of the foot. Acute injury or cumulative trauma to the plantar fascia can be a cause of inflammation and heel pain. This is called plantar fasciitis.
Plantar fasciitis occurs when the ligament in your foot arch is strained repeatedly, which causes tiny tears and significant pain. There are several possible causes for this condition. Excessive pronation, or overpronation, which happens when your feet roll excessively inward as you walk. Flat feet or high arches. Walking, standing, or running for long periods of time, particularly on hard surfaces (a common problem for athletes). Excess weight, such as overweight or obesity. Shoes that are worn out or don’t fit well. Tight calf muscles or Achilles tendons.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as arthritis, or a nerve problem such as tarsal tunnel syndrome.
Physical examination is the best way to determine if you have plantar fasciitis. Your doctor examines the affected area to determine if plantar fasciitis is the cause of your pain. The doctor may also examine you while you are sitting, standing, and walking. It is important to discuss your daily routine with your doctor. An occupation in which you stand for long periods of time may cause plantar fasciitis. An X-ray may reveal a heel spur. The actual heel spur is not painful. The presence of a heel spur suggests that the plantar fascia has been pulled and stretched excessively for a long period of time, sometimes months or years. If you have plantar fasciitis, you may or may not have a heel spur. Even if your plantar fasciitis becomes less bothersome, the heel spur will remain.
Non Surgical Treatment
Over-the-counter arch supports may be useful in patients with acute plantar fasciitis and mild pes planus. The support provided by over-the-counter arch supports is highly variable and depends on the material used to make the support. In general, patients should try to find the most dense material that is soft enough to be comfortable to walk on. Over-the-counter arch supports are especially useful in the treatment of adolescents whose rapid foot growth may require a new pair of arch supports once or more per season. Custom orthotics are usually made by taking a plaster cast or an impression of the individual's foot and then constructing an insert specifically designed to control biomechanical risk factors such as pes planus, valgus heel alignment and discrepancies in leg length. For patients with plantar fasciitis, the most common prescription is for semi-rigid, three-quarters to full-length orthotics with longitudinal arch support. Two important characteristics for successful treatment of plantar fasciitis with orthotics are the need to control over-pronation and metatarsal head motion, especially of the first metatarsal head. In one study, orthotics were cited by 27 percent of patients as the best treatment. The main disadvantage of orthotics is the cost, which may range from $75 to $300 or more and which is frequently not covered by health insurance.
When more-conservative measures aren't working, your doctor might recommend steroid shots. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple injections aren't recommended because they can weaken your plantar fascia and possibly cause it to rupture, as well as shrink the fat pad covering your heel bone. Extracorporeal shock wave therapy. In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It's usually used for chronic plantar fasciitis that hasn't responded to more-conservative treatments. This procedure may cause bruises, swelling, pain, numbness or tingling and has not been shown to be consistently effective. Surgery. Few people need surgery to detach the plantar fascia from the heel bone. It's generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
Making sure your ankle, Achilles tendon, and calf muscles are flexible can help prevent plantar fasciitis. Stretch your plantar fascia in the morning before you get out of bed. Doing activities in moderation can also help.
