I'd really appreciate help on how to get my mum's GP to give her B12 injections. My mother has had MS for over 40 years now. She has also been type II diabetic and taken metformin for over 10 years at least. Recently she went into hospital and was taken off metformin. The situation is complicated, however, I still think that her symptoms are neurological and she is entitled to get a proper diagnosis. So far the GP has said that her blood cells are not enlarged so she is not showing signs of low B12. My aunt, who does have 3-monthly injections in West Wales, has said that she needs to have a specialist test. Mum is in Wiltshire and tests are limited it seems. Her nerve damage is caused by MS, however, there could be a link. She has a very small appetite and unlikely to eat enough high B12 foods. Please can you advise how I arrange for my Mum to have a test and be given an injection?
