Question -
would you prefer to,
A) Go to A&E now, get the all clear (fingers crossed) and be able to sleep tonight knowing you protected youe child as best you could
B) Go to A&E now and get a dianosis (hopefully he wont have it) and get treatment started and know you did the best for your child
C) stay at home, worry all night, not sleep and feel bad that you didnt go, or worse stay at home and he gets really ill.
I know thats a very black and white way to look at it but i really want you to go get him checked out. Please! Better to be safe than so very sorry.
