My 2 month old had a 102 degree fever last night ten days after immunizations. Could it be from them that long ago? I took her to the emergency room, they were not sure, they just said to bring her back if she starts acting funny. She narrowly escaped a spinal tap!!! They said if she was two weeks younger they would have done the spinal tap regardless of bloodwork. Is that typical? Aren't spinal taps risky and painful?
