Re: could this be Raynaud's
I've had Raynaud's for a while now. My fingers change colour depending on what stage of the attack they are at. When they are completely white (or an odd yellowy green colour in my case) that generally is the most severe point of the attack and an indication that there is very little blood getting through. My fingers are completely numb at this point. As the attack subsides my fingers go tingly and burny. They go a blue black colour and then a roary red colour. Raynaud's can be related to Rheumatoid Arthritis - though I am no expert. I take tablets for it - unfortunately I still get attacks but they are less severe and less frequent. I tend to wear two pairs of gloves and thermal socks to avoid attacts. I hate the dairy section in the supermarket! You should have someone look at your hands. That way you will know for definite.
