Agatha, everything seemed excellent until I came to the slurring of speech. It must be rather worrying. My speech had become very slurred before I started treatment but it quickly righted itself after a few weeks. During treatment and even beyond, if I am very tired or stressed it can re-appear to a lesser extent, due to the fact that new pathways are just that so are never as good as the original ones.
However, you say you didn't have slurring before: I had one episode when I had been on abx for more than six months, where I discovered on kneeling down that my left leg was completely numb up to and beyond the patella. Even though it didn't last very long, it scared me rather. I was due for another MRI a few months later and I wondered what would be found. Actually, there was nothing new at all and in fact it was the MRI when several lesions were found to have vanished. So I guess this could be a similar episode.
I have never been very good at living for the moment so I can appreciate your worry. However from my experience it might very well just be a minor blip. guess your work involves a lot of talking and if you are worried it will appear even worse.
