Check Homocysteine: Elevated homocysteine levels are a good marker for nerve damage due to B12 and Folic Acid deficiency. Even with normal levels of these two chemicals your body may not be able to use and you need to take the methyl- varieties and can lead to functional deficiency leading to neuropathy. There is test that looks at the small fibers that get affected by these conditions and diabetes. Ask your doc.

I recommend SL: You want to keep your B12 level above 350. 1.2 mg sublingually is cheap and generally effective. The problem with B12 is absorbing it 99 percent of the time.
