Plantar fasciitis is the most common cause of heel pain in grown-ups. The strong ligament is a robust tissue on the underside of the foot's surface that attaches the heel bone to the forefoot, thus plays a very important role in supporting the arch of the foot. As the foot's arch is subjected under pressure, it may cause pain in the heel area. https://www.sooperarticles.com/health-fitness-articles/diseases-articles/there-no-one-treatment-plantar-fasciitis-1899775.html
