Plantar Fasciitis Causes Pain And Stiffness In The Sole Of Runners

Also called fasciitis, a problem arises from an inflammation caused by tension and overloading the area from overuse which can cause knee pain from running (วิ่ง แล้ว เจ็บ เข่า which is the term in Thai).

For those who practice street running, the feet can be the focus of injuries due to the nature of the physical activity. And one of the most common problems in this part of the body is plantar fasciitis. It is felt through a pinch in the sole, which appears because the area has a natural curvature and needs to accommodate the ground. That is, this tension ends up overloading their structures. Overuse can lead to inflammation, pain, and stiffness in the region.

Plantar Fasciitis Or Muscle Tension? Learn To Identify And Treat Foot Pain

Plantar fasciitis is an inflammation of the dense tissue in the sole, which occurs due to excessive exertion in the region. This tissue is called the plantar fascia, an aponeurosis (tissue that covers the musculature of the sole) that extends from the calcaneus, the bone that forms the heel, to the toes. It helps maintain the foot’s longitudinal arch. Running and walking increase the force exerted on the foot even more, when the overload exceeds the foot’s capacity to absorb trauma, hence the pain. The weakness of the muscles to absorb this impact influences.


  • Changes in the formation of the arch of the feet;
  • Wrong step;
  • Shortening of the Achilles tendon and posterior leg muscles;
  • Excessive strain on the sole

How To Avoid

  • Run-on soft terrain;
  • Muscle-strengthening;
  • Always stretch before and after running;
  • Excessive weight loss;
  • Padded heel insoles to minimize fascia stretch and reduce impact absorption.


Initially, treating the lesion is always conservative, being done with anti-inflammatory drugs and analgesics. Physical therapy with exercises to stretch the plantar fascia and Achilles’ tendon (hamstring tendon) is also essential.
