A 62-year-old man has presented with a complex heel condition in his right foot. He has been informed that he is suffering from plantar fasciitis and his condition has been going on for almost a year and a half. The ultrasound report confirms a mild case of plantar fasciitis. Moreover, he demonstrates typical symptoms of plantar fasciitis in that he feels a significant pain each morning when his heel is placed on the ground. The pain dissipates within the first 10 to 15 minutes of his day.
However, the pain around the lateral side of his heel persists throughout the day and does not seem to ease. He remembers having 3 recent ankle sprains in short succession. What is the next best step in the management of this condition?
