What your feet say about your health

Heel pain

The most common cause of heel pain is plantar fasciitis, inflammation where this long ligament attaches to the heel bone. The pain may be sharpest when you first wake up and put pressure on the foot. Arthritis, excessive exercise, and poorly fitting shoes also can cause heel pain, as can tendonitis. Less common causes include a bone spur on the bottom of the heel, a bone infection, tumor, or fracture.

Dragging your feet

Sometimes the first sign of a problem is a change in the way you walk — a wider gait or slight foot dragging. The cause may be the slow loss of normal sensation in your feet, brought on by peripheral nerve damage. About 30% of these cases are linked to diabetes. Nerve damage also can be due to infection, vitamin deficiency, and alcoholism. In many cases, no one knows what caused the nerve damage. Other possible causes for foot dragging include problems with the brain, spinal cord, or muscles.
