I've already been diagnosed I was just wondering if there are any tests that recommend why I have it. Over time it has gotten worse over the last two years but it consists of burning, tingling and overall burning at first in my legs and full body but over time it stopped. And since then every day randomly i'd get a random sensation along with it become easier for my limbs to fall asleep/ feeling lost little by little. It gets worse when I wakeup and eat high carb/sugary meals but I stopped that a while ago. and now im losing sensation everywhere in my body and it has progressed really far and it gives me anxiety and stress everyday. But this is full body neuropathy and mostly effects my sensory nerves.
