6 year old daughter: Ear infection over 1 and a half weeks ago: took all meds. Back at DR on Monday, (3 days after finishing meds) she had fever over weekend and complained of sore calf muscles. At Dr. today! Complete blood work done today waiting till Monday for results. She wakes up middle of the night crying, calf/leg pain. She had fever 99.4 today, swollen glands, coughing and is stiff when she wakes. She has not missed one day of school so she is not sick often!!!! Any thoughts? When she has motrin in her he jumps rope and plays for a while! Can a virus cause these symptoms? She was tested for JRA and lyme, she also had complete CBC work up today.
