For the last month I've had a minty sensation in my mouth, my tongue feels cold and the back is numb. Its almost like the feeling you get when you first put minty gum in your mouth, but I've not eaten gum for over a month. Also My finger tips lack sensation. I've also been experiencing dizziness over the same duration of one month. I can't recall any injuries. My current health issues include hypothyroidism, severe RLS, and memory loss. Other then that I'm a happy healthy 34 year old female. Any suggestions?
