I've had a variety of symptoms for 6-8 years. Specialists believed it was "something autoimmune" but had no definite diagnosis. This year old symptoms are worse with new symptoms. I have memory & word-finding problems, falling frequently, heat intolerance, sleeplessness, nightmares with only occasional flashes of memory about them, & constipation with some diarrhea. Within the last month I've lost bladder then bowel control multiple times and developed nonstop severe hand & leg tremors which lasted two weeks & have now diminished to mild but return to severe with exertion such as taking a shower. Also, I can't perform finger-to-nose or heel-to-toe tests. I would greatly appreciate any help you can provide.
