What is Plantar Fasciitis And its Causes?

Plantar Fasciitis is a disorder that results in pain in the heel and bottom of the foot. The pain is usually most severe with the first steps of the day or following a period of rest. The condition typically comes on slowly. In about a third of people both legs are affected. 

Risk factors for plantar fasciitis include overuse such as from long periods of standing, an increase in exercise, and obesity. It is also associated with inward rolling of the foot and a lifestyle that involves little exercise. While heel spurs are frequently found it is unclear if they have a role in causing the condition. Plantar fasciitis is a disorder of the insertion site of the ligament on the bone characterized by micro tears, breakdown of collagen, and scarring. The diagnosis is typically based on signs and symptoms with ultrasound sometimes used to help. Other conditions with similar symptoms include osteoarthritis, ankylosing spondylitis, heel pad syndrome, and reactive arthritis.
