So, my son is 13 yo.
we had 2 IVIG's in the past. never checked for lyme or any other co infektions.
We are now 11 weeks post 2.nd ivig. My son's tics are now much better, but I feel that they will come back. I don't know why, but I think that this betterment now is not because of IVIG, than because of the waxing and wanning..so, I'm allreday checking for some other option.
What are Your experience with PEX after unsecsessfull ivig?
