Our 14 month old grandson has been running a fever of 104 off and on now for about six weeks. He had Coxackie for about two weeks. It ran its course. Then he had a sinus infection. Then Coxackie again. Ran its course. Then he was diagnosed with an ear infection, prescribed antibiotic. Fever went away, returned. This time a double ear infection. Another round of antibiotics. Cleared up. Fever returned after about five days. Pediatrician said it was just a virus. Fever returned. Another MD prescribed another round of antibiotics. Seemed to clear up again for past 7 days. Tonight he came home from day care and running another Fever of 104. This is getting a bit scary. Can you give us any thoughts?
