I have had symptoms similar to this, light pin-pricks at various locations, usually arms and legs. Also occasional I was able to reverse this, make it happen much less frequent, through diet and exercise. I use the principles endorsed by Dr. Dean Ornish, Dr. Andrew Weil, Dr. Mark Hyman, and others. I don't want to speak for them so look them up, but here is my interpretation:

Eat mostly fruits, vegetables, and whole grains.
Avoid meats rich in saturated fat such as beef & pork.
Eat foods with low glycemic load, to keep blood sugar low.
Avoid refined carbohydrates such as products containing flour.
Eat good fats such as nuts, canola oil, olive oil, soybeans, salmon.
Avoid food additives.

What we eat actually affects our bodies. (Imagine that!) I also believe exercise is important. I have not yet established whether the diet or exercise is most helpful to me, or if they are perhaps about equal. I lift dumbells, do sit-ups, leg lifts, push-ups etc. for 45-60 minutes, 3 times a week. It helps me to watch a TV show I like.

Some foods I like to eat:
All-Bran and Raisin Bran cereals
soy milk (less sugar and sat. fat than cow's milk)
mix of edamame (from frozen), peas (from frozen), and whole grain noodles
grilled salmon
grilled vegetables (asparagus, bell peppers, onions, etc.) in foil
home-cooked pinto beans
walnuts, almonds, cashews
dark chocolate (70-80% cacao)
figs
prunes
bananas
low-fat, low sugar yogurt (tough to find)

I also take a multi-vitamin, B-50 complex, B12, evening primrose oil, and alpha-lipoic acid. I believe the latter two help with my neuropathy pain.
