Can I just say that I'm following this thread with interest because my pain doc has promised to look into IVIg for me.....
Ambica - you've given some really valuable and interesting information about this so thank you but you are posting some of the same information about your experience in nearly every post and it is getting a little repetitive in places!
No offence intended at all, I'm sure people are reading the thread and realise how passionate you are about this subject, but I am starting to skip parts of your posts because they seem to be the same information - and obviously that's not good because if there is something new I'm going to miss it.

Take care everyone and I hope you have a good day today

Bram.
