Dear Doc, Well I have a very peculiar problem with my 7 month old boy, well He is absolutely normal and meeting all the milestones for his age, but one concern when ever he gets a fever his frontal ( soft tissue on the head ) gets bulged / swollen, I took him to many hospitals locally here and consulted doctors even did a spine tap and found the suspected infections for menigintis to be NEGATIVE , even took ultra sound for his head soft tissue and it also came to be OK , all are surprised with this, don t know why this happens, I am just starting to get worried, other wise his activities and activeness is all fine , I want to seek an opinion from the experts in this regard
