Hello. I am so sorry you are going through this. I am fairly new here too. And, still learning.
Have you had mono, had a tick bite? So many things can have these symptoms. I assume you are seeing a neurologist. Hopefully they look at blood work for inherited diseases, heavy metals, other tests that may indicate pre-diabetes.
Hope you find answers and relief. You have found the right place to search for answers and give you tips on care. Best wishes.
