Hi all, I'm a 38 year old female with a tingly tongue, feet and hands. Occasionally I feel tingles up my arm or leg and head and face. I had a brain and cervical MRI and all came back normal. It's not vitamin deficiency, diabetics or ms, from what docs tell me. I have noticed my vision gets blurry at times. I don't take any medications. Anyone else have any idea what this could be? Could I have ms with a negative MRI? Any answers appreciated! ~J
