Thanks for replying everyone..

I forgot to mention two new symptoms, an increased need to go to the toilet, particularly during the night and a constant dry mouth and gritty eyes, I'm thinking autonomic dysfunction(or Sjorgren's) from what I've read.
Between 5am and 11am this morning I had to go 10 times!

I tried to eat a lot in Italy, but my apetite was quite poor. The food was pretty much what I would eat at home (pasta, fish, fresh veg).
I have lost so much weight. At first it was because I wasn't eating beacause of worry, but I've been eating normally for a few weeks and I'm still losing it.

I'm having a camera down my throat on Wednesday and am seeing a neurologist on Friday (waited 6 weeks for this appointment). I can't wait now. I'm taking a symptoms list as long as my arm!

I am very worried about what is causing all of this and am thinking the worst.
I know there are more than 100 causes of PN and 400 autoimmune diseases that mimic the symptoms of MS but some of the treatable ones have been ruled out by blood tests already (thyroid, diabetes, B12).

I'm fed up.
Thanks for your support..
