It usually results from excessive mechanical stress on the foot, particularly due to sports activities, inadequate footwear, or activity overload.<\/p>\n<p>This condition mainly affects people who participate in impact sports as well as workers who remain standing or walk for prolonged periods.<\/p>\n<p><strong>The main symptoms<\/strong> of plantar fasciitis include:<\/p>\n<ul>\n<li>pain under the heel,<\/li>\n<li>more pronounced pain during the first steps in the morning,<\/li>\n<li>a sharp or needle-like sensation under the foot,<\/li>\n<li>plantar stiffness after a period of sitting or rest.<\/li>\n<\/ul>\n<p><strong>Symptom intensity<\/strong> may vary depending on:<\/p>\n<ul>\n<li>the level of weight-bearing physical activity (walking, jumping, running),<\/li>\n<li>the type of footwear worn,<\/li>\n<li>the amount of weight transmitted to the feet (body weight and carrying loads, when applicable),<\/li>\n<li>the stage of the condition and how symptoms have been managed since their onset.<\/li>\n<\/ul>\n<h2>Why do I have heel pain or pain under my foot?<\/h2>\n<h3>Mechanical stress<\/h3>\n<p>Plantar fasciitis is mainly related to an overload of mechanical stress transmitted to the foot. This overload can occur when the plantar fascia is subjected to demands that are too great or increase too quickly relative to its ability to adapt.<\/p>\n<div class=\"accordeons\">\n<div class=\"su-accordion su-u-trim\">\n<div class=\"su-spoiler su-spoiler-style-default su-spoiler-icon-plus su-spoiler-closed\" data-scroll-offset=\"0\" data-anchor-in-url=\"no\"><h3 class=\"su-spoiler-title\" tabindex=\"0\" role=\"button\"><span class=\"su-spoiler-icon\"><\/span>Rapid increase in activities<\/h3><div class=\"su-spoiler-content su-u-clearfix su-u-trim\">\n<p>Introducing a new impact sport, such as running or sports involving jumping, without sufficient progression may contribute to the onset of symptoms.
