I was diagnosed with MS a few months ago, the diagnosis having been clinched by a Lumbar Puncture. Having done my reseach, including reading many of the helpful posts on this forum, I asked my GP for a blood test for Vit B12 along with one for Vit D3. The first B12 test came back as deficient with a level of 135 so my GP asked me to take a 2nd test to look at intrinsic factor. Have just phoned the surgery and been told this is normal - a level of 80. I do not think my diet is low in B12 so if it is not my diet and not a problem with absorption caused by dodgy intrinsic factor, what is causing the B12 deficiency? Any ideas anyone before I speak to my doctor on Thursday? Am due also to see my MS Nurse on 2 April - will she be able to advise on thi?. Will I still be offered B12 injections? Have been getting a lot of tingling lately which I hoped might be alleviated by B12 injections so will be disappointed if she says these are not required.
