Plantar fasciitis is a type of aseptic inflammation. In diagnosis, there is usually a history of chronic strain in the plantar area, or frequent exposure to cold. Patients may feel stabbing pain in the plantar area, swelling in the plantar muscles and fascia tissues, widespread tenderness, and some exhibit definite tender points, affecting normal plantar activity. There is fascial tissue adhesion; when touching the plantar area, the skin may also feel hard and tight. Ultrasonography and MRI can be conducted, and combined with physical examination, a definitive diagnosis can be made. In treatment, conservative methods are used. Often soaking feet in warm water, applying external ointments that invigorate blood circulation and reduce stasis, performing acupuncture and moxibustion, strengthening exercises for the plantar muscle tissues, and taking oral nonsteroidal anti-inflammatory and analgesic drugs.
