Is B12 level of 256 low enough to need treated?

[RubySparks]

I have been having what could be symptoms of b12 deficiency for nearly a year - pins and needles/tingling sensations in feet and legs but also hands and face, sore tongue for last month and lots of trouble remembering and concentrating.

I had b12 blood test last week and result was 256 with range of 180 - 2000.

I also have coeliac disease and hashimoto's hypothyroidism so have never been quite sure if problems were due to those or something else....

Anyone been treated at these levels or have any suggestions?

I had not been able to remember my dreams for years and had been sacked by a psychotherapist because of it - and then I got on thryoxine and not being able to remember them is a sign I need to up my dose.

Aargh this is the problem I don't know what is thyroid problem and what is something else! Been on levothyroxine for a few years now though and this is first time I have really noticed the dreaming thing - it seems to make my brain feel better too when I've been dreaming.

Had last b12 injection today, next one in 3 months.... My head is clear and more energy but bad pins and needles and very tingly / sore tongue just hoping it calms down soon.
