CHARLESTON, W.Va. -- Dear Cindy,

Being a longtime walker, I attempted to kick my fitness up a notch by jogging. I did it gradually adding some short periods of running so basically it was a walk/run workout. Things seemed to be going well until I noticed a pain in my right heel. It has gotten worse and forced me to go back to walking again, and still it has not gone away. I am 42 and never had a problem with my foot before this, so is jogging out of the question for me? -- Sondra

Dear Sondra,

More than likely you are describing a fairly common overuse syndrome known as plantar fasciitis -- inflammation of the thick band of tissue that runs through the bottom of your foot and connects your heel bone to your toes. Everyone who has ever experienced that stabbing pain can relate to your question. Revving up your exercise regimen -- jogging instead of walking -- is certainly not out of the question; however, to make this problem go away, it's important to understand what made it show up in the first place.

Risk factors for developing plantar fasciitis:

Is it me?

Contacting the ground with the foot misaligned can cause plantar fasciitis, which, left untreated, may progress into knee, hip or back issues. If poor mechanics is identified as the cause, seek the advice of a professional, a podiatrist or foot specialist, or this will be a chronic problem each time you resume the activity.

Are you a pronator?

More than likely, you are one of the above. You'll hear the terms "pronation" (inward roll of the foot) and "supination" (outward roll of the foot) when discussing proper body mechanics. Pronation is often blamed for creating plantar fasciitis though this is not the case. In fact, these terms refer to the natural rolling movement of your foot while walking or running. You would find it difficult if not impossible to walk or run without pronation and supination.

However, when there is excessive pronation, it can have negative effects on the health of your feet. This is why it's important to get advice from a foot specialist and then choose shoes that can reduce excessive rolling of the feet.

Are your muscles tight?

While the way your foot strikes the ground during a walk or a run is definitely a factor, too often muscle imbalances are overlooked as the underlying cause. Stretching your plantar fascia gently, as well as your calf muscles and Achilles' tendon, will go a long way toward healing and preventing this painful condition.

What to do

First and foremost, because this is considered an overuse injury, you need to curb your activity and possibly stop activity to give the small tears in your fascia time to heal. This includes walking because that repetitive stress will keep it irritated and inflamed. Other recommendations include:
