Oh my goodness.....that is a huge laundry list...I am soooooo sorry that you are experiencing all of these neurological things.
I have the fog...extreme at times, and I lose words also.
The involintary movements sounds like definate neurology problems. The times that I have that is when I am having something called seizure play...I don't mean actually any kind of seizure, though. For me it means to run and not walk and take my Tegregol because I am late or have forgotten it. (I am epileptic)
I dont' have any of the other things, though...I freeze in the winter. So cold that it hurts. Ant I definately feel hot in the summer. The hot sometimes makes me so weak that I can't get up the next day.( that possibly could be the sun and not just the heat) I am still new to the diagnosis. I have been ill on again off again for years, though.
I will be interested to hear what your neurologist thinks...or does he? Sometimes I think I understand what they mean when the doc will say that he "practices" medicine....oh well...practice makes perfect, so someday they might get it right.
I look forward to getting to know you better,
I have promises to keep and miles to go before I sleep, and miles to go before I sleep.......Robert Frost
