Hey thank you very much. That is helpful. I have the same sort of difficulties with speech that you mention. I probably use speech impediment as short hand to describe what's happening. The neurologist in 2013 was almost certain that I had MS but all tests came back clear. Most medical people who see me presume I have MS because of the way I move. The hospital refuses to retest me. This week my GP confirmed she believes I have fibromyalgia (alongside the neurological and pain disorder)and she is allowed to diagnose me so next week I'm contacting the Arthritis foundation. Thanks for replying to my post. All the best.
