--though, given your GERD proton pump inhibitor history, one does immediately wonder about nutrient malabsorption, which leads one also to wonder about the possibility of celiac/gluten sensitivity.

You also mention those very high triglycerides; there are some isolated cases of neuropathy associated with that. Are these the result of heredity (if you know)? In other cases it tends to be dietary; you don't mention weight, which can also contribute to nerve compression (in truth, neuropathy associated with hypertriglyceridemia also tends to be associated with pre-diabetes/metabolic syndrome in those whose triglyceride levels cannot be traced to hereditary factors).

There is a list of tests that many of us refer to that helps to suggest investigative avenues and is also good for tracking tests results over time--the Liza Jane spreadsheets:

You can look that over and see what you've had done so far and what might be good to try and get done (it takes a very savvy physician to know the protocols and algorithms to try to diagnose neuropathy; most are not familiar with many of the serologic tests:
