Immunity, high fever, vom, h. Pure veg!

Your history is difficult to understand.excpt child having squint probably from birth, Recurring infection headache, vomiting and fever. I think you are following with your pediatrician regularly? He must have kept something in mind regarding this illness, whether child is suffering from any immunological condition where child can get recurring infection. As there are many such conditions with this problem,so many investigations but sometimes nothing comes positive. In such cases lot of team work matter,like your eye specialist doctor, pediatrician etc. I can recommend get some opinion from Genetic specialist.? Immunologist,you can may be find them in Big, hospital institute in your City. Advising more without seeing patient and other investigation on such platform it's of no help .
