Mild Vit D deficiency may cause paresthesias, due to poor calcium control in the body. Improving your Vit D may help the tingling. Do 2000IU D3 daily for a month or two and see if there is any difference.
The low range in your test results is not really normal. You should really be at 150 or so (your units).
It would not hurt to try some methylcobalamin... 1000mcg daily orally on an empty stomach, and see if there is any change.
Another cause for numb feelings and tingling are episodes of low blood sugar. So if you log the times you get them, compare to what you ate before--up to 6 hrs before---to see if they come more often with high carb intakes (as opposed to high protein intake).
