I stared to feel very faint, and got pins and needles all down the right side of my body. My husband was really concerned (and I was getting a bit scared too, started wondering if I was having a stroke, and I'm only 46).
I saw two doctors, who did lots of tests of my reflexes, co-ordination and sensitivity. They ruled out a stroke, thank god, and said my symptoms were most likely due to my B12 deficiency. The first doctor was going to give me a b12 injection, but then managed to view my GP records on the computer, and noticed that my last blood test (20 Dec) showed my B12 was just back into the normal range, but commented that I may need to be 'normal' for a while ,before the symptoms stop. This is interesting though, because it means that the cyanocobalamin tablets I was taking (from the doctor) seem to have increased my B12 levels, so I assume this is good news as it rules out an absorption problem?
The hospital did another B12 test while I was there, and said my GP should be able to access this. I was feeling quite a lot better by this time, and thankfully they allowed me to go home.
So I will be back to see my GP next week, although as the b12 supplements seem to be working, I'm not sure if she'll do anything? But in the meantime I've started taking the Jarrow Methyl B12 lozenges 1000mcg. I'm going to take two per day to give myself a boost.
