I am 78 and surgery has never been offered or mentioned at all. I was diagnosed 2 years ago. I was immediatly put on IVIG. I received it monthly. I felt terrific. My doctor moved out of town. Now with new doctor I am living a nightmare. She put be on Gammagard. I now have liver pain. Constant yellow diarrea. And feel like Gumby! (Gumby was a carton years ago. He was rubber. When he walked his arms and legs were wobbley). I spoke with my doctor and asked to be put back on IVIG. She agreed. Besides mestanon I receive monthly infusions. I am being put back on Human immunoglobulin! Yeah!!!!
