Hi Gagalina:

Do you mean paresthesia? It feels like pins and needles in your fingers? If so, I get the same thing when I keep my carbs too low. Is it the same sensation as when you are startled? I actually wrote to Atkins about this and they said they've never head of it before. However, I've seen several posts on the boards about it.

My personal theory is that it's an adrenaline reaction from tightly controlling insulin, forcing the liver to create glucose (gluconeogenesis). I often get it when I'm weightlifting and at the slightest increase in stress.

Obviously, it's not a common reaction, but for me, I needed to increase my carbs a bit for it to go away. You might try it and see what happens.

But it wouldn't hurt to see a doctor about it b/c the symptom is indicative of more serious illness like MS.
