okay, okay, first of all, calm down, you are not going to be any help to ds at all if you are worked up.
Secondly, what does the answerphone say? is the consultant gone for the day or just not available right now?
All this latest thing means is that the consultant presumably has the results back and wants to discuss them with you. It could be that they are completely fine and he wants to tell you himself.
There is absolutely nothing you can do until you have spoken to the consultant, so keep trying him, or leave a message on his answerphone, but in the meantime try to stay calm.
Whatever the outcome, your little boy is going to be in the best hands and will have lots of people caring for him, especially a nice, calm mummy.
You could try ringing your GP I suppose and seeing if they can tell you anything.
Now make yourself a cup of tea and have a biscuit, try to pretend everything is perfectly normal.
