Plantar fasciitis is inflammation of the thick tissue on the bottom of the foot. This tissue is called the plantar fascia. It connects the heel bone to the toes and creates the arch of the foot. Night Splints aid in prevention of this inflammation by giving a passive stretch. 

Causes, incidence, and risk factors

Plantar fasciitis occurs when the thick band of tissue on the bottom of the foot is overstretched or overused. This can be painful and make walking more difficult.

Risk factors for plantar fasciitis include:

  • Foot arch problems (both flat feet and high arches)

  • Obesity or sudden weight gain

  • Long-distance running, especially running downhill or on uneven surfaces

  • Sudden weight gain

  • Tight Achilles tendon (the tendon connecting the calf muscles to the heel)

  • Shoes with poor arch support or soft soles

Plantar fasciitis most often affects active men ages 40 - 70. It is one of the most common orthopedic complaints relating to the foot.

Plantar fasciitis is commonly thought of as being caused by a heel spur, but research has found that this is not the case. On x-ray, heel spurs are seen in people with and without plantar fasciitis.


The most common complaint is pain and stiffness in the bottom of the heel. The heel pain may be dull or sharp. The bottom of the foot may also ache or burn.

The pain is usually worse:

  • In the morning when you take your first steps

  • After standing or sitting for a while

  • When climbing stairs

  • After intense activity

The pain may develop slowly over time, or suddenly after intense activity.

Signs and tests

The doctor will perform a physical exam. This may show:

  • Tenderness on the bottom of your foot

  • Flat feet or high arches

  • Mild foot swelling or redness

  • Stiffness or tightness of the arch in the bottom of your foot.

X-rays may be taken to rule out other problems, but having a heel spur is not significant.


Your doctor will usually first recommend:

  • Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) to reduce pain and inflammation

  • Heel stretching exercises

  • Resting as much as possible for at least a week

  • Wearing shoes with good support and cushions

Other steps to relieve pain include:

If these treatments do not work, your doctor may recommend:

  • Wearing a Cam Walker, which looks like a ski boot, for 3-6 weeks. It can be removed for bathing.

  • Custom-made shoe inserts (orthotics)

  • Steroid shots or injections into the heel

In a few patients, nonsurgical treatment does not work. Surgery to release the tight tissue becomes necessary.

Expectations (prognosis)

Nonsurgical treatments almost always improve the pain. Treatment can last from several months to 2 years before symptoms get better. Most patients feel better in 9 months. Some people need surgery to relieve the pain.


Pain may continue despite treatment. Some people may need surgery. Surgery has its own risks. Talk to your doctor about the risks of surgery.

Calling your health care provider

Contact your health care provider if you have symptoms of plantar fasciitis.


Making sure your ankle, Achilles tendon, and calf muscles are flexible can help prevent plantar fasciitis.
