I second what the others have said. Watch for a rash. My son had a fever up to 105 and no other symptoms but a small drip from his nose due to the fever being so high. He was out playing like normal at 104 and at 105 he just wanted to be cuddled. When I called my doctor about the fever I was told to watch him if it went above 104 get to the hospital right away. Well he was missed diagnosed at the hospital-he did have mildly swollen glands and red throat and her ears were a little red -from such a high fever. He was misdiagnosed with upper respiratory infection and ear infection. Well once the fever broke a rash came 3 days later. I thought it was another allergic reaction to antibiotics. Nope his pediatrician said stop antibiotics he has Roseola. He never needed the antibiotics! UGH! I even questioned the ER doctor about the antibiotics because I did not feel they were needed.
