Right after surgery (2yrsAgo)I developed an autonomic nervous system dysfunction and ever since my liver enzymes (labs)fluctuate normal and high cause?

LFT elevation. Intermittent LFT increase associated with variety of illness most commonly non alcoholic fatty liver (or alcohol) Also viral hepatitis, medications / drugs or exposure to certain chemicals. To be sure this can get complicated so should probably see doc to make sure you have been tested for the major causes before thinking about many, many less common things.
