My lb turned 3 in September and also started nursery, 3rd week into school his leg was buckling and he developed a limp, A&E diagnosed irritable hip (no tests done just physical examination), a week later he got a cold which turned into an ear infection, since that we've had 6 ear infections in 7 months all accompanied by fevers some high some medium. He's also had 3 viral rashes, 3 separate coughs, one of which lasted for 8 weeks from Dec-Feb. He's had a few (maybe 3-4 in the 7 months) night time complaints of leg pain, either massage or calpol resolved these. Last week he got another fever for 3&half days, the morning after it broke on Sunday past he started with another limp (this time a lot milder than September leg wasn't giving way on him at least) back to A&E who again diagnosed irritable hip, this time a urine test was done which was clear. Since this he has had 2 evenings of cold sweats with low body temps of 35.5 or thereabouts, he's not soaked through or anything but hair is wet, skin is cold to touch, pj's at nape of neck are damp. Am I being crazy to think this could be leukemia? My friend has a lb same age also in preschool who has had just as many infections as my lb this autumn/winter (different kinds though chest infection, tonsillitis etc) which makes me think this amount of illness is normal but combined with the leg issues and now some night sweats? My husband thinks I'm totally crazy, he says the leg pain at night is growing pains, and 2 episodes of irritable hip are not unheard of. He's been referred to ENT next month btw for the ear infections and congestion to have adenoids looked into. Any opinions welcome. Should I go to gp (for gazillionth time) and ask for a blood test and outright say I'm worried he has leukemia?!
