Today after an hour car journey we walked to a restaurant for lunch (was quite cold) and I noticed my left middle finger had pins and needles and when I looked at it, it was totally white at the end.
Whilst sat in the restaurant I massaged this finger for a few minutes and the pinkness came back and the pins and needles disappeared.
Have never had this before, but have heard about it in workmen using drilling machinery.
Anyone know anything about this and was it just the cold that caused it?
