Hi Erin -
Sorry to hear about the trouble with your PICC line. I get IVIG every three weeks - finally hada permanent port placed in my chest wall about 1 1/2 years ago. When I first had IVIG they used the veins in my arms and hands until they couldn't - then suggested a port. It took a long time for me to agree to it - felt like another concession to this disease that I didn't want to make. Now I can honestly say it was one of the better choices I have made. It takes them about 10 seconds to access the port and hook me up for my infusions. It is under my skin so not as much risk of infection. Not sure how often you will have to get IVIG but if it turns into something long term it might be something to consider.
