My son n law went to er with Dx of heat stroke, temp 103.9, wbc s 14, he has had ice packs ice water baths etc temp still 103.3, he had some n/v, pale, c/o back and neck pain, states neck is not really stiff ...it s been almost 5 hours, and no break in temp, I m not sure how long he had temp before he went to er..He has been admitted to ccu, he responding etc...i think he needs spinal tap, how long can you run that kind of temp without damage of some kind My daughter had meningitis as a baby, so I tend to always think about that first
