It is not CFS, it is mercury. My burning mouth and tingling tongue started a few weeks ago. My upper lip also started getting numb. Sometimes my tongue tickles, sometimes it feels cold, sometimes it's just numb. Every SINGLE thing you list, I have too. It took me a long time to realize what was wrong with me. Now you know, so be at peace with that. You can now decide how you want to proceed.

I have been fumbling my words for years, and I never knew why. I felt like my brain and mouth were NOT connected, because what I really WANT to say, is not what comes out. I also started transposing numbers and letters when I typed at my job (when I used to work) and it made things very difficult. I couldn't understand where this all was coming from, and I thought I was losing my mind. Thank God I have spell check, and can read and re-read things when I type. It makes me very sad, though. Now I am doing it when I write by hand too.

I would love to talk with you more, Fiona. BTW my name is Lisa, and I'm glad you found your way here.
