Hi Dr Smith, thanks for your reply. I read up on here as much as I could find. I have this week been diagnosed with PA, so that is a start. I seem to be lucky enough to have a doctor straight off the bat who seems to know what he is talking about, although it seems a shame I suffered so long without seeking help, and we hope some of the neurological and nerve issues resolve themselves over time, my levels are still only at 119 pmol/L. I'm now on x3 1000mcg a month of B12 shots indefinitely until it gets up there than we review the injections, and getting a double dose of 2000mcg next week as I'm off to the US next Friday.
