The diagnosis of plantar fasciitis relies on the doctor's physical examination, the patient's symptoms, and imaging tests which serve as auxiliary examinations. These tests help to rule out other conditions such as bone spurs or osteoarthritis, as well as other abnormal lesions. Once these possibilities are excluded, a diagnosis of plantar fasciitis can be made. Typically, there are specific tender points on the foot, which could be singular or multiple. Improvements can often be achieved through appropriate measures such as heat application, physical therapy, rest, and, if necessary, electrical stimulation or pain point injection treatment. However, excessive weight-bearing activities could potentially lead to a recurrence of the symptoms in the later stages.
