Did the afteraffects of the infusion go away yet? Your body should be getting used to getting them by now - I would definatley contact your nurologist about whats going on - as mentioned - you may need a different type or different dose....

I had of new brand if IVIG this past week - and started getting real sick the minute they started infusing it - that was Wednesday - they only got thru a quarter of it - stopping three times to get to that point - and am still feeling very bad - have orders from the neruo to go to ER if they continue... your neruo really needs to know what is happening... hope you are feeling better by now!
