Yes I would try gluten free. You have to do it for several months or a year though to really see a difference if there is going to be one.

The nerves could have been damaged some by your previous work. They don't always show that damage right away...there is a cushion of sorts, before they reach a point where things become symptomatic. Pile on other triggers over time, and they add up and bingo...

I'd avoid vaccines from now on, unless there is a compelling pandemic or the like. They tend to trigger autoimmune reactions in people with inherited tendencies for this.

Autonomic neuropathies are peripheral too...they are unmyelinated fibers, like some of the sensory ones.

You might try using acetyl carnitine up to 2 grams a day in divided doses to see if there is any change. Expect 3 months to show a change. This supplement enhances fatty acid metabolism instead of glucose in the mitochondria. Damaged mitochondria may respond to this.

I'd also cut out the carbs and sugars as much as possible. Also watch your triglyerides. When high these clog up the blood vessels and impair circulation to the periphery and the nerves suffer then. This fish oil lowers triglycerides BTW.

Using Omega-3 fish oils or Krill oil, may help with any inflammatory issues you have.
Look up the Zone diet....it is very good at controlling blood sugars and also helps reduce inflammation.

Magnesium lotion may be helpful for specific targets. When calcium and magnesium go out of balance, face tingling may occur. This lotion is really nice and provides the magnesium you need because some is absorbed. The rest blocks the NMDA pain receptors, improves blood flow and stops any cramping of muscles.
This is the affordable one many of us use with success:

This is also in most local WalMarts, and Walgreen's.
Apply to only intact skin, avoid eye areas, and don't slather it on. A little goes a long way. If you have many spots to put it on, rotate them daily with other areas. Too much may make you tired, sleepy etc. I use this every day and it has been fabulous for me and many others here at NT.
