My 4 year old daughter just got over a cold. She now has a lot of goop in her eyes, she has been very tired, emotional, and moody. She keeps saying she is thirsty, but doesn t drink much more than normal. She isn t sleeping well, and when she wakes up at night she will complain about her feet, hands, or arms hurting, but I can t see anything physically wrong. I am going to call her doctor tomorrow but don t know how to help her. What could be wrong?
