What are the side effects of IVIG if any that anyone has seen?

[Guest guest]

I posted on here a while ago about my son Gestin. He is now almost 3.

We have been fighting to get him on IVIG, but nobody would say do it.

We thought a while ago that we would do it,but the immunologist keeps

on testing and testing, but won't go ahead with treatment. We went to

Gestin's new ENT on Thursday and he said he needs IVIG. Gestin has

polyps disease serverly and his sinuses have been cloged for 6 months.

He is going in this Thursday for a clean out of his sinuses, but after

this we are going ahead. I just want to know what are some side

effects of the IVIG. I am a bit worried because I don't want him to

hurt more than he already has. If anyone can help please let me know.

Please keep Gestin in your prayers.
