I'm sorry that I do not know the size for IV IG cuz' I've only ever had a PICC line put in me. If you are afraid of needles and don't want stick after stick, perhaps you can ask about that option - especially since they will want to do lab work as well. Once the line is in, it's smooth sailing, and I'm the biggest chicken there is when it comes to needles.

You'll probably love IV IG - I know in my case it was truly a life saver - I've had 3 treatments for 5 days straight and felt like a champ once they were done - MUCH better than plasmaphoresis and MUCH less invasive - in my opinion - GOOD LUCK and let us all know how you are doing!

Take care!
