Re: Dark purple colored toenails
It does not sound like Raynaud's as the dusky , or blue/purple phase affects the toe itself and is caused by lack of oxygen. It doesn't change the colour of the nail. If digit itself is this colour and has remained so this long, you should definitely call your Dr. If it is just the nail, have you worn any dark coloured polish of late? That might be causing the purply colour of the nail itself, and yellowing can be caused by chemicals and fungus infections and such. You can certainly consult your Dr about fungal infections.
