Since last Tuesday, Katie, who is stoic about any discomfort, has had unceasing pain around her knee. Some friends were over during our long power outage yesterday evening and the kids ran around for hours outside in the darkness. Afterward, Katie's pain was so bad that she had Advil, ice packs, and a Tiger Balm massage by Becky before bed. After tucking Katie in with an elevated and immobilized leg, big sister took to Dr. Google to try to find a diagnosis for her kid sister. To her credit, she hit upon Osgood-Schlatter disease in her search, and today our doctor confirmed her guess. So Katie gets three days of limited activity and a cool nickname, "Ozzy."
