So glad the IVIG is helping. I know that I have to medicate myself after the IVIG with pain meds if I feel the slightest headache coming on to combat it. Also I take benadryl the nights I have IVIG to counteract any side effects from the IVIG. I also have issues with nausea and have meds to work with those side effects. You just have to try and catch any side effects before they start when you get home from the IVIG after the treatments. It has worked for me and I hope it works for you. I agree, you have to tell the nurses how you are feeling and take care of yourself first and don't be in any hurry. Each of us is different and don't always fit into a certain schedule for the infusions. Best wishes for your next IVIG.
Hugs,
Simon
