Fasciitis of the foot mainly occurs in areas of the foot where there is a concentration of weight: the first area is the front part of the sole, the forefoot, which is the weight-bearing part of the foot and is equivalent to the metatarsophalangeal joint. The second part is the heel of the foot, which is the location of weight-bearing contact with the ground, and is also the place where the weight is concentrated. The third part is the middle of the plantar area, where the metatarsal tendon membrane, which maintains the stability of the foot arch, is prone to inflammation. The corresponding weight-bearing is also greater to maintain the stability of the foot arch. Therefore, the tendonitis of the foot mainly arises in the parts of the foot where the weight is more concentrated and heavy, which are the three parts mentioned above. Tendonitis of the plantar aspect of the foot can be treated with symptomatic support therapy, physical therapy, closed injection therapy, daily maintenance, etc. for recovery and treatment.
