@naturegirl5 Thanks for your wise advice! I appreciate your mentorship! I have applied your advice to my situation! After the Mayo Clinic diagnosis, I discussed your proposal to help me, with my immunologist! Thus, he prescribed the correct gamma globulin medicine, for me, and his nurse manager is lining up an I-V fusion facility ( Vivo ), near me, where a pro. nurse will set up, and administer the I-V fusion therapy, for the prescribed dosage, and time period! Also, she will make sure that Medicare, and Secondary Insurance approval of payment for services rendered, is taken care of. So, she said she wants to make it stress free, for me, and that others with my same or similar diagnosis, have been approved by their insurance companies, so she expects I will be approved to! This would be a big burden lifted off my concerns, because it seems like my inflammatory polyneuropathy is creeping further up my legs and arms, and the electric shock like buzz feeling that I get, in my legs, is more pronounced! So, I need help and relief soon! Thanks a million for your advocacy and wise advice! I will be forever indebted to you for your help!
