Erin, your symptoms sound like mine from this post. I am fairly new and have not corresponded with you previously. Since I can't see your post at this time, I can't remember exactly what you called it, but what IS an IV IG? What is the nature of your treated condition? I really appreciate the information. I would have sent this by PM, but my connector is malfunctioning. Thank You. And I AM praying for you! billie
