I am having a real problem with 3 things not sure if they are all related or not #1 I sweat Real bad the thing is i only sweat in areas that are touching something like if i am sitting down my back sied of my body will sweat but not the frount. if i wear my hair down my neck will sweat but not if ti is up. #2 my nails on my hands are turing down. #3 my hands are very sensitive to cold to the point i have a hard time puting ice in a glass it makes them hurt.
