My 8 year old son has had the flu for almost a week. He had some vomiting initially, with complaints of a sore stomache. That has seemed to subside. He now complains of having sore knees, is barely able to tolerate standing or even walking. He is still quite congested and has a bad cough . He hasn t complained of a sore back or neck. If I was to take him in to the doctor, what would they do to assess him and rule out meningitis without taking the lumbar puncture? Obviously that is not the road I want to go down unless it was absolutely necessary and meningitis was a serious concern. Without seeing him, what would be your first questions to assess his condition and rule out meningitis? It is flu season and I know it s going around, so I don t want to be a hypochondriac, but the sore legs threw me since he has never complained about that before.
