YES: Some experts suggest anyone with a B12 level below 450 who has symptoms suggestive of B12 deficiency be treated. Some people will respond to high doses of oral or sublingual B12 but if that dose not increase your levels you should get injections. I don't see why you should have to fight to get these.
