Reynauds? DH had just one finger turn completely white & go numb today. Not cold. Suggestions?

[Milliways]

A few years ago DH had to give up a self employed car franchise as he was suffering with a sort of RSI of his hand, from polishing cars etc. Hand kept swelling up & going tingly but no other symptoms.

Today, he was rubbing down a small area on our old car to respray it and came in as just ONE of his fingers had gone numb (index finger).

He thought the colour was from filler, but it was totally colourless - no blood at all. I made him put hand down for blood to get in there, and with massage and time it did pink up again but had pins & needles for a bit.

Very odd? Just one finger and hand felt fine (previous problem was hand and not fingers an no symptoms for 2-3 years now).

Reynauds comes up on google - but can you get it in your 40's in just 1 finger?

Any ideas?

I get this (undiagnosed but fairly sure it's reynauds) and it doesn't always happen cos of it being cold, worst for me is driving, even in the summer, two or three fingers just go 'dead'- quick remedy is putting them in warm water but it is very painful, much better to let them 'come back'on their own!

There are things the doc can do,I think BP tablets is one answer? If it bothers him he could pop along to the doctor.

Thank you

I will send him to Docs if it re-occurs.
