Had a strange little conversation with nurse yesterday:
me: How many patients have you got with functional B12 deficiency?
nurse, bit cagey: Two or three
(me being one)
me: Have you ever had any before?
nurse shakes her head and looks straight at me: This is a new thing, this is a new thing.
me, probably pushing my luck: Would you at some point consider teaching us how to self-inject safely, as a group?
nurse: It's very difficult to self-inject in your own arm.
me: Can't it be injected anywhere where it's not likely to hit a vein- your thigh, say?
nurse: No- apparently, it has to go into your arm, for absorption reasons.
Well, she didn't get cross with me for making the suggestion anyway.
