Anything unusual here?
See link (https://healthunlocked.com/pasoc/posts/135301103/very-confused) for background, but as a quick summary, my B12 serum is now good after taking sublingual supplements for the last several months (>2000). Yet I am still having low B12 symptoms, particularly feeling cold, shortness of breath, and neurological. Also, lowish RBC, highish MCV still.
Judging from these tests results, should I just give up on thinking that my problems are B12 related? I originally tested in the low 200's prior to beginning treatment.
