Hi all, I am at wits end, my son finally got IVIG last week, all be it only 40 g, not the HD I was wanting but replacement dose for his immune deficiency. so now his tics are like twice as bad, could be from the stress of it all but I am worried we made his encephalitis worse. He has had these terrible explosive barking/grunting noises that happen non stop, it hurts him so much and stressed him so bad it makes the rages worse also. anyone else experience worsening of tics after IVIG and what helped, nothing I try is helping...
