My daughter has been having issues with her fingers turning blue. It happens at different times and places. It will wipe off, but returns in a matter of minutes. She has also see her thighs start to turn blue. She has dizzy spells, feels faint and has had some joint pain. Blood tests are within normal ranges, they tested for heavy metal poisoning-neg. Except for high ana titer. We are currently waiting for appointment with Rheumatologist.
