Hello~Have they checked you M.S., or Fibromyalgia? I would sure get a second opinion if possible from a different neurologist. In the meantime, I know this will sound odd, but try a chiropractor, if you have any nerve impingements, they can cause some of the issues you are having, also, start taking a high potency B complex, a good multi mineral with high calcium and magnesium, and Gingko for the memory.
I had the same symptoms and all my heart tests and CT scans were normal.
My issue was due to anemia, low ferritin, low Vitamin D, low magnesium and I took Vitamin B12 (wasn't tested)
It took a couple of months to see improvements.
I not sure .I would go with checking the heart yet I am not a professional yet it sound scary, sorry for that: but of courses you should get another opinion
