Stewart decides to go see Dr. Waring so that he can ask about the open sore on his leg that has been there for over a month and is not healing. Stewart dreads seeing him again because at his last visit Stewart promised to exercise more and eat a healthier diet.

Stewart hobbles into the exam room where the nurse takes his vital signs and records them for the physician to reference. When Dr. Waring enters the room, he reviews Stewart’s vitals and health history. Dr. Waring asks to see the sore on his leg. Stewart lies down and the physician inspects the oozing wound on his right leg and asks Stewart how he has been treating the wound. Stewart replies that he has been using an over-the-counter topical antibiotic. The physician asks Stewart if he has had a lack of feeling in his feet. Stewart thinks for a minute and says yes, but he thought it was just because of his extra weight.
