So my story started 2 years ago with all types of neurological symptoms, vertigo, nausea and vision problems. Finally after many dr visits I got told I have low b12- 220ml they started me on weekly injections (only wanted to give me three) but symptoms got worse at first so I ended up having 9 all up. Symptoms finally disappeared (not completely) levels went to 925ml then then send me on my way. Three months later symptoms started again but with pins and needles and numbness in my arms,legs and face. Went for tests results were 350ml- 'normal' they said. Reluctantly started me on injections again but want to do every 3 months. Now off to a neurologist for a MRI and dr mentioned MS. Any advise or help on this topic?!? No IF antibodies present. But feel like my levels shouldn't have dropped almost 500mls in three months. GP says 'normal'
