I started a gluten free diet 3 weeks ago. I have been bedbound for 11 years witha diagnosis of cfs. I have been feeling a bit more clear headed but the last week ive started to slur my words. Ive never had this before. Today people cant understand me at all. Its really got me quite scared. I think my tongue is swollen. Why is this happening? I know i havent accidently eaten any gluten. Would really appreciate some help, thanks. Leis.
