Ada Hunt







Ada Hunt is a 31-year-old customer service representative with the chief complaint of, “I pulled something in my foot, so I can’t exercise.” She explained to me, “Doctor, I have to exercise if I’m ever going to lose this weight. And I was doing so well! I’ve already lost 40 pounds. I just have to exercise, or I am dead.” Ada went on to say that since the weather got cold, she had been running on a treadmill rather than outside. The pain came on gradually, but it is so bad that it now hurts to bear any weight on her left foot. “Doctor, I got a new pair of running shoes, but that didn’t help. What am I going to do? I’m really having a hard time getting better in spite of massage, acupuncture, aromatherapy, Motrin, and a lidocaine patch.” She said she took a few pain pills that she had left over from having her wisdom teeth pulled, but they seized up her bowels, so she quit taking them, too.


I asked Ada if she ever had anything like this before, and she shook her head no. She also denied any current urinary or gynecologic symptoms, hematuria, or fever or chills. She also denied a history of previous foot or ankle injuries. Her last menstrual period was about 10 days ago. Ada is using oral contraceptives. I asked what she was currently doing to manage the pain, and she said, “Nothing really works—the Motrin barely takes the edge off.” I asked her to rate her pain on a scale of 1 to 10, with 10 being the worst pain she ever had. She said the pain was a 7 or 8. “Doctor, I have to get back to normal. I have to exercise. The pain is interfering with just about everything. I can’t walk, I can’t run, I can’t do aerobics. I am having a hard time getting around. I just really need to get my life back.”


I asked Ada to point with one finger to show me where it hurt the most. She pointed to the medial longitudinal arch of her foot, and said, “Doc, the pain is right here, right under the bone. It’s really killing me.”


On physical examination, Ada was afebrile. Her respirations were 16. Her pulse was 72 and regular, and her blood pressure was normal at 118/68. Her weight was 276 pounds. Her head, eyes, ears, nose, throat (HEENT) exam was normal, as was her thyroid examination. Her cardiopulmonary examination was negative. Her abdominal examination revealed no abnormal mass or organomegaly, and no groin mass or hernia was identified. There was no costovertebral angle (CVA) tenderness. There was no peripheral edema. Her low back examination was unremarkable. Her lower extremity neurologic examination was completely normal, with no evidence of tarsal tunnel syndrome. There was point tenderness over the medial longitudinal arch on the left. Active resisted inversion of the ankle reproduced the pain, as did passively flexing the left foot. Visual inspection of the arch revealed no ecchymosis or fibromatosis, but swelling and erythema was noted ( Fig. 13.1 ). “Ada, how about walking down the hall for me?” She carefully sat up and slid off the exam table. As she took off down the hall, I immediately noticed that she had an antalgic gait and was avoiding weight bearing on the left foot.
