Hi Lauren ! I would like to know if your son is getting
fever either low or high grade in between. The symtoms you have mentioned are pointing to infection in the course of the shunt . It could be the
peritoneal cavity (abdominal cavity). I would suggest you to contact your doctor/
pediatrician at the earliest, who may apart from clinically examining him suggest some blood tests for your son to see if there are any features of infection. I hope this should help you in dealing with the situation. Good luck.
