HI Melody!
The IV is Immune globulin (intravenous) (IGIV) It's used to strengthen muscles and nerves.......but you have to take it weekly (an hr long IV session) for the rest of your life! So it's not a fix.....just a bandaid that makes you feel better. It's a combination of 40+ people's blood to make this serum and the article I read on Google said it's screened for diseases and virus's but there's no guarantee that you won't catch something from it.....tho the odds are very low. With all the problems I already have I don't think I want to take this chance of catching something that someone else had! My Rheumatologist is looking into the IV situation tho.
No, I don't take Methylcobalimin B-12 (but will look into that!) I take the Twinlab formula of vegetarian B-12 Dots Sublingually. They are only 500mg. My B-12 isn't low (from the blood tests that's been taken recently). I take this brand only because my Gastro dr. who did my Gastric Bypass recommened it. I'm not sure I can take the Methyl type because I have Interstatial Cystitis......it might throw my bladder into a flare.

But it might be worth trying to see if it would or not.....at this point I'll try about anything!
I'm SO depressed since I've had Neuropathy and all the testing I've had to do....I just wish I could get the pain under control.....or feel like I'm getting a handle on it! Roxie
