Hi gfields!-
I have Raynaud's. I have seen my finger tips turn blue. My feet are a lot worse. I have seen my toes turn completely white and very cold from having lack of blood flow.
When the blood flow returns to my toes, they turn purple/blue. Then turn bright red and burn very bad.
Last winter, my toes were swollen, bright red, severely itchy, and pealing a thin layer of skin. I found out that it was Chilblains.
If you are interested, here is a website about
Lyme, Raynaud's, and Chilblains.

I hope that you are able to get some answers from your doctors appointment in September.
Best Wishes!
