Overview
Plantar fasciitis is the common label for pain where the plantar fascia attaches near the inside-bottom of the heel. The familiar pattern is pain with the first steps in the morning or after sitting, which eases somewhat with movement and may build again with longer activity.
Why It Develops
It often follows a mismatch between foot-load demands and current capacity: a jump in walking, standing, running, hills or body weight can contribute. Reduced ankle movement, calf weakness, footwear and recovery can all influence symptoms. It is not simply a “heel spur” problem and a spur on an X-ray does not prove it is the pain source.
What Usually Helps
Good first steps include education, adjusting aggravating activity without becoming completely inactive, plantar-fascia and calf stretching, comfortable footwear, and progressive foot/calf strength. Taping or orthoses can be useful for some people as part of a broader plan, not as a permanent cure.
When To Get Checked
Get assessed for severe pain after trauma, inability to bear weight, numbness/burning, swelling or redness, fever, pain at rest/night, or symptoms that keep worsening despite sensible load changes. These patterns can point to another cause of heel pain.
