Hi, I'm very much hoping that someone here will be able to help me. Just before Christmas I started having tingling feelings in my feet and hands. These spread to other parts of my body, and can now occur anywhere. I also get fasciculations. I've had some tests from my GP, but he seems a bit out of his depth with it. My B12 was low and I tested positive for anti-parietal antibodies. In a subsequent stool test I also tested positive for malabsorption. I was treated with six hydroxocobalam injections, plus a three monthly injection, but from what I've read on this site that won't be enough to sort out the neurological symptoms, so I've been supplementing with methylcobalamin on my own - I've tried patches and 1000 mcg per day orally, but the symptoms are very slow to settle down, and they get much worse when I eat a whole range of foods (gluten, dairy, and apparently almost anything high in fructose - I ate some apple the other day and the paresthesia started up within five minutes). I'm assuming I probably have low stomach acid (I tried taking some bicarbonate of soda, and didn't burp at all, and when I asked him the doctor said it was a "no-brainer" that I would have low stomach acid, though he hadn't mentioned it to me). Does anyone else here have neurological symptoms which can come on incredibly fast after eating particular foods? It would be really helpful to know that I'm not alone with these puzzling symptoms. Thanks in advance for any help!
