If you are having a blood sugar problem, that can cause nerve damage and tingling. Nerve damage is often associated with diabetes. You can ask your doctor to check your A1C level to get an idea how it has been doing.
It would probably help your glucose levels to stick with a paleo style diet, avoiding most carbs. Carbs and meats have a different affect on blood glucose. Carbs tend to spike blood glucose while meats even it out.
There are a lot of negative changes that can happen with high blood glucose. It is wise to try and get it under control ASAP. My brother has lost most of his vision in one eye now from high blood glucose. And he has the tingling symptoms you described. The tingling can progress to pain in time. My brother chose to ignore his diabetes and is paying the price for it. He is doing better at it now but the damage is done.
Yes, B-12 deficiency can cause those kind of nerve symptoms. But if you have high blood sugar that is the more common cause. Diabetes is not a rare condition.
I have been living in Ho Chi Minh City, Vietnam, for two years, and finding gluten-free food is proving more difficult than I thought, even if I am cooking my own food. Wheat flour, called "bot mi" in Vietnamese, seems to creep into a lot of stuff nowadays. What's more, manufacturers do not feel it is important to list bot mi in the ingredients on a food's packaging unless it is a principle ingredient in the food. In other words, soy sauces or wraps with just a tiny bit of wheat flour added to add a touch of thickness or pliability are not guaranteed to list the ingredient. For some genetic reason, Vietnamese people are not nearly as susceptible to food allergies as Westerners - it probably has something to do with exposure to less hygenic foodstuffs having built up an immunity over hundreds of years - so it is not really considered important to split hairs in that department over here.
Anyway, I love rice paper but have often gotten glutened by it when I have it. Can any celiac who could tell if a product had gluten by more than just the ingredient list on the back let me know a definitively gluten-free rice paper brand? I know that very few rice paper brands actually list wheat flour in the ingredients, but I don't 100% trust the ingredients list for products made by Vietnamese companies. Call me paranoid.
By the way, I have a neurological condition that irreversably breaks down my immune system when I ingest gluten, so I don't want to experiment with trial by fire here.
