My problem must be familiar to many on this site. I had extreme liver failure in 1984 and was in a coma for 6 weeks. Since then my liver does not appear to be able to store B12 properly. My blood levels with 1ml of methylcobolamin injection every three months are barely above the minimum. Oral does not work for me. In the third months my symptoms become severe. I am buying in hydroxocobolamin and self-injecting to survive. My GP will not agree to giving me more B12 even on a private prescription and does not seem to care about (or believe) the symptoms. I am desperate. Can anyone advise how to get out of this impasse. The NHS has failed me (they caused the liver failure in the first place) and I need to take my health into my own hands despite their obstruction. I am looking for injectable Methylcobolamin but would prefer not to buy it off the Web but will do so if that is the only route to avoid nerve damage. Pleeease Help!
