Have your doctor challenge the insurance company. He/she can site the fact that you are immune-suppressed, and the cost factors can be outlined, as home IVIG is much less expensive that that at an infusion center. My doctors have always been happy to help with letters, phone calls, etc. Don't be afraid to ask.

Prednisone would be an inexpensive and relatively quick thing to try as well, but of course you know it comes with side effects and risks. I am one of the few who doesn't absolutely hate it. I've not had the massive wt gain but did have moon face, mood disturbance, insomnia, etc on high doses. I'm currently weaning off of it, for about the 3rd time and am currently on 7.5 mg eod. I've been on it the better part of 12 years. My bones remain good, no cataracts.

Be careful right now. Call your doctor first thing on Monday, and sooner if you fall again!

Good luck.
