Results: 42% identi�ed pain as a symptom, and among those, 60% reported severe pain. Pain di�ered among participants in severity, type, location, duration, frequency, and quality. Additionally, the average of total percent of body surface that participants had shaded as painful was 20%. Leg pain was the most common anatomical site of pain followed by arm pain and back pain.
