Artchick,
I am glad that you are doing better today
Sometimes IVIG reactions are just plain confusing. I've been getting IVIG infusions for 5 years now and always start low at 35.They increase it slowly and usually my max rate is 240.
Sometimes I can go as high as 280 but if I get that "funny feeling" then my nurse will go slow it down. I get them at home and have had the same Nurse for about 4 years so she knows me and my body well.
I hope you continue to feel better and you won't have problems with your next infusion. As always keep telling them how you feel during the infusion and insist that they slow it down when you start feeling bad. You know your body better than anyone else and only you can tell them what you are feeling like at that given moment. They have to listen to you and slow it down when your body is reacting to it.
Blessings,
Shari
