I have colitis and my stomach was starting to get upset and I don t know if my colitis had anything to do with it but suddenly I felt a tingly feeling and numbness in both my hands and legs...it was really hard for me to move my fingers and I started sweating purposely...I had to lay down on the bathroom floor because I was freaking out and I had to aim the fan towards me to feel cooled down a little. This lasted for several minutes before I felt normal again.
