Hi, I have had tingling in my legs for the last two weeks. It started in the front of my legs near my ankles and slowly spread to my feet and up my legs. This is constant and when I stand up after sitting for a while, my feet cramp and hurt to walk on. My hands tingle occasionally, and today my face has started to tingle too! I am also very fatigued and feel dizzy sometimes when I am sitting or lying down. I am a 45 year old female. Can anyone please give me some idea what this could be? Thanks
