That is wonderful that your husband got a pump! I have been receiving IVIG therapy for the past 8 months now and it is very frustrating working from a drip.
I know exactly what you are saying about some nurses wanting to speed things up. I finally have a lovely nurse that helps me know, but the first one was awful! She was insisting on giving me 35gms in 1 1/2 to 2 hours. By the time she was done my head was spinning. When my doctor increased my dose to 80 gms she wanted to give it to me in 3-4 hour. I never let her touch me again and got rid of her immediately!
