I downloaded the PDF check from the pernicious anaemia society website and scored 66. (http://www.pernicious-anaemia-society.org/SYMCHV2-Could-you-be-B12-deficient-2013.pdf)
Have been suffering from the effects for years and after a couple of close relatives where diagnosed with PA I decided to look into it.
I bought some B12 (hydroxocobalamin) depots from a German company and have been injecting myself for about 2 weeks. Got the needles from medisave.co.uk/ was all fairly easy and then looked up injecting intra muscularly on youtube etc. I'm not squeamish so that definitely helps
I'm feeling dramatically better already, looking forward to more improvements and moving into the maintenance stage.
