Hi my DS is 22 months. This year I've been very concerned about his health. On 26th Jan he had a temperature lasting 12 days which was finally diagnosed as the flu via swab. 10 days later he got another cold with fever. 20 days later he got a 38.5 temperature for 8 hours and 4 days later another temperature rising to 39.7 overnight. He still currently has this latest temperature. I'm now starting to worry that it isn't normal to have this many temperatures especially with the last one being unexplained. Could it be leukemia? Has anyone got experience of childhood leukemia and are these recurring and frequent temperatures a likely sign of this? Freaking out!
