I am having symptoms where my arms go numb from my finger tips to my chest (sometimes just from my forearm to my chest) and I get REALLY dizzy. It's almost like extreme vertigo, but I can still slowly function, I just feel out of it and shaky. I do not have earaches or headaches and no muscle pain. These are the only two symptoms I have other than a stiff neck. And I take medicine for hypothyriodism. Any idea what this could be? I just recently stopped eating red meat too, if that is relevant. I am also 26 years old. Thanks.
