Kay, it sounds like your daughter is fighting the same thing KC was. She was sick with an ear infection and on 2 antibiotics for 10 days with a low grade temp. She felt better for a few days and the temp. came back with a stomach pain and nausea. I took her back to the Dr. but they couldn't detect any infection. I had her on triple dose Cortef and several injections over a 14 day period. She went back to school yesterday feeling better but looking peaked. With all the Cortef she kept an appetite but I had to stay on her about fluids( she's 11 also and knows all) I thought for a while she would be hospitalized, it seemed like she would never get better, she still complains of being tired but is over the hump, I hope your daughter feels better soon.
