1.What is plantar fasciitis? It is also known as jogger’s heel, which occurs in special athletes and long-distance runners who run more, and is characterized by pain in the heel and plantar area. 2, is plantar fasciitis really an inflammation of the plantar fascia? The traditional view is that plantar fasciitis is caused by inflammation of the plantar fascia attachment due to repeated, excessive strain and use over a long period of time. In fact, repetitive studies have shown that plantar fascial pain occurs without inflammation but rather with degenerative tissue changes, so the use of anti-inflammatory drugs in treatment has proven to be ineffective. The real name for plantar fasciitis should be degenerative changes of the plantar. 3, the plantar fascia degenerative changes occur due to (1) excessive weight gain; (2) incorrect choice of shoes; (3) flat feet; (4) high arches; (5) trauma; (6) calf muscle tension; (7) strenuous sports; (8) prolonged standing; (9) obesity. 4.Does the pain occur only in the heel? In a 2013 study, a number of patients were diagnosed with ultrasound and found that the degenerative changes in the plantar area were scattered, not just around the heel. 5. Difference from a bone spur in the heel When a bone spur develops in the heel, it also shows pain, but the pain occurs when the heel is in contact with the ground, whereas plantar fasciitis pain tends to occur when the foot is stirred off the ground. When bone spurs appear the pain is worst at night before going to bed, while in plantar fasciitis the pain is worst in the early morning before waking up. Overweight people are most likely to develop heel spurs, and changes in the mechanics of the foot predispose to plantar fasciitis. The most important thing to prevent heel spurs is to have a proper diet and weight control, and surgery is needed to remove the spurs if they are severe, while physical therapy is mostly used for plantar fasciitis.
