Plantar fasciitis is one of the most common explanations of heel pain. It is caused by inflammation to the thick band that connects the toes to the heel bone, called the plantar fascia, which runs across the bottom of your foot. The condition is most commonly seen in runners, pregnant women, overweight people, and individuals who wear inadequately supporting shoes. Plantar fasciitis typically affects people between the ages of 40 and 70.
The plantar fascia is designed to absorb the high stresses and strains we place on our feet. But, sometimes, too much pressure damages or tears the tissues. The body's natural response to injury is inflammation, which results in the heel pain and stiffness of plantar fasciitis.
The condition typically starts gradually with mild pain at the heel bone often referred to as a stone bruise. You're more likely to feel it after (not during) exercise. The pain classically occurs right after getting up in the morning and after a period of sitting. If you don't treat plantar fasciitis, it may become a chronic condition. You may not be able to keep up your level of activity, and you may develop symptoms of foot, knee, hip and back problems because plantar fasciitis can change the way you walk.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
Most doctors recommend an initial six- to eight-week program of conservative treatment, including Rest, balanced with stretching exercises to lengthen the heel cord and plantar fascia. Ice massage to the bottom of the foot after activities that trigger heel pain. Avoidance of walking barefoot or wearing slippers or sandals that provide little arch support. A temporary switch to swimming and/or bicycling instead of sports that involve running and jumping. Shoes with soft heels and insoles. Taping the bottom of the injured foot. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin and other brand names), or acetaminophen (Tylenol) for pain. Physical therapy using ultrasound, electrical stimulation with corticosteroids or massage techniques. If this conservative treatment does not help, your doctor may recommend that you wear a night splint for six to eight weeks. While you sleep, the night splint will keep your foot in a neutral or slightly flexed (bent) position to help maintain the normal stretch of the plantar fascia and heel cord. If the night splint doesn't work, your doctor may inject corticosteroid medication into the painful area or place your foot in a short leg cast for one to three months. Shock wave therapy, in which focused sound energy is applied to the sore heel, may be recommended for plantar fasciitis. The shock waves are intended to irritate or injure the plantar fascia to promote healing. The overall benefit of this approach is uncertain. Other therapies that have been tried include radiation therapy and botulinum toxin injections. But their effectiveness is unclear. If all else fails, your doctor may suggest surgery. But this is rare, and surgery is not always successful.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament. Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause nerve damage.
