Hi all,
I’ve been having pretty constant parasthesias on both sides of my body usually worse from shoulders down to fingers, initial B12 level was 190 (was 845 four years ago).
New doctor had me test for IF antibodies immediately after giving me a B12 injection which was negative and she stated later the timing would have affected it. Switched doctors and am now on weekly B12 but around day 4 or 5 the parasthesias come back full force and are unrelenting. Prior to starting any injections my parietal cell antibody test was positive but completely normal gastrin - I would assume gastrin would be high as my new dr suspects PA.
Had endoscopy and colonoscopy that showed only patchy erythema so GI doc said I’m normal but afterwards she learned about PCAB positive test and said she’d redo endoscopy because she might have missed something.
What are your thoughts? Shouldn’t gastrin and MMA be high with positive PCAB and wouldn’t positive PCAB lead to IF antibodies?
Neurologist consult said if I had PA I’d have parasthesias on lower legs before anything so it’s not possible. She ordered nerve conduction study and cervical MRI.
would love to hear your thoughts or similar experiences.
Thanks!
Katie
