Because of the history of FM in the family I am paying attention to my children as they grow up. When my 7 year old son has fevers, he always get nausea and vomits even if he just has a cold fever. There are no exceptions- as the temperature is there, he WILL vomit. This seem to me to be a sensitive nervous system which I can relate to myself, and as I grew up I got unusual sensations (nerve) from fevers too. He says to me one morning a week ago that he sometimes feel nauseous when he wakes up in the morning. His balance have been very sensitive, I can tell on the playground now and in the past where spinning was something he could not tolerate. He got an inherited heart murmur (HunkPapa Sioux) that have not grown away, but they said it seem to be ok now. I know heart murmurs usually grows away, but it has not in his case, and when they remain they can grow into heart problems when they grow oder (adults). Sometimes I wonder if it's signs of FM/CFS in childhood, or that his heart murmur is causing more issues than they can see on an echo cardiogram. He is sensitive to warm weather which seem to fatigue him and make him tired, he goes indoors and sit down by the TV, even if his best buddy (neighbor) is outside. I am of course going to find him a different pediatrician than the current (no-good) one, but I would like to hear from you if you have any experience at all with this kind of stuff. I have that sixth sense feeling I have to keep an eye on things, if you know what I mean. Any input would be helpful!
