Long-distance running, especially running downhill or on uneven surfaces
Sudden weight gain or obesity
Tight Achilles tendon (the tendon connecting the calf muscles to the heel)
Shoes with poor arch support or soft soles
Plantar fasciitis is seen in both men and women. However, it 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 health care provider 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.
Your health care provider will usually first recommend:
Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) to reduce pain and inflammation
Heel and foot stretching exercises
Night splints to wear while sleeping to stretch the foot
Resting as much as possible for at least a week
Wearing shoes with good support and cushions
Other steps to relieve pain include:
Apply ice to the painful area. Do this at least twice a day for 10 - 15 minutes, more often in the first couple of days.
Try wearing a heel cup, felt pads in the heel area, or shoe inserts.
Use night splints to stretch the injured fascia and allow it to heal.
If these treatments do not work, your health care provider may recommend:
Wearing a boot cast, 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
Sometimes, foot surgery is needed.
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.
