I experience tingling in my arm, fingers, and toes. Sometimes I am also experiencing numbness. It doesn't last all day, but it is worst at night time. I went to a neurologist and was told to ake a motrin if it helps and come back in a month. He gave me a nerve ending tests and didn't find anything. I also had a MRI and found a slight bulging disc, but the dr. said they will watch it. How do I know if I have Vitamin B12 defiency. Oh yes, my other blood work came back normal. I thought I had diabetes, but that test was normal. I don't know what is causing the tingling or needle sensation feeling.
