I don't know what to research anymore, so I'm here hoping someone might have a clue. Several months ago, I was having a lot of problems with numbness/tingling in my hands, feet, and right quad, almost exclusively occurring at night and/or upon waking. If I laid down long enough, something would go numb. They would wake back up when I moved them though, but skip the buzzing stage that usually happens when your limbs fall asleep. I was under a doctor's care (for a whole host of symptoms...terribly insomnia, gastro, menstual issues among them). I got tested for vit B12 and vit D deficiency. I corrected it, but it didn't help with the numbness/tingling issues, I've also been tested for pre-menopause, diabetes, thyroid issues, polymyositis, Chron's, lupus, etc.) Everything is fine/normal. I'm not even pre-diabetic. Because of my other symptoms, I suspected that I had celiac/gluten intolerance. I cut gluten from my diet, and after three days, the numbness went away (actually 90% of my symptoms went away). Since the numbness had spread to my face the very last day I felt it (while I was AWAKE) I was ecstatic. Unfortunately or fortunately, I was mostly just eating meat, veg, and fruit those days. The first time I ate a gluten-free product made from corn meal, my hands/feet went numb again. It only happened that one night/morning instead of three. It happened again three times: when I had wild rice, sugar, and bananas. I cut all grains and sugar from my diet then (except potatoes and all fruit but bananas). The numbness in my hands and feet stopped, all except for two accidents. I tried a vitamin and woke up with numb hands. Turns out the vitamin used polydextrose as a filler (I thought it said NO SUGAR on the label instead of NO ARTIFICIAL SUGAR). I also tried to add normal, white rice back into my diet and had the same numbness problem. Luckily, it didn't linger. None of this numbness happens right after eating though. It happens HOURS AND HOURS later (except with the chocolate bar(sugar)...that time it happened within about 30 minutes or an hour...but I was also laying down). I've asked several of my doctors if this numbness thing could be a blood sugar problem. They say no, but they've also said a whole lot other boneheaded ****, so my trust in doctors is fading. I've seen two family practice doctors, a PA, a neurologist, and a GI, No one knows anything. No one will help me. I've only gotten this far from internet research and trial and error, and darn it, I need to know what I can safely eat and what I can't. I've unintentionally dropped from 150 pounds to 116 pounds since July. I'm fading away.
