Plantar Fasciitis
Inflammation or degeneration of the plantar fascia — the thick band of tissue connecting the heel bone to the toes. Causes sharp pain on the underside of the heel that is worst with first steps in the morning.
Affects up to 15% of the population at some point. Twice as common in women than men. Most prevalent in people aged 40 to 60.
Key difference from other causes: The morning start-up pain pattern and the specific tender spot on the underside of the heel.
Treatment summary: Daily stretching exercises, foot taping, footwear changes. See our full guide.
