No but I have a nail turning brown. The foot doctor was totally puzzled by. I will run that by her. It's not athlete foot or a fungus. Complete mystery. But she had me soak it in a listen and apple cider vinegar bath for 20 minutes 2x weekly and then use Vicks Vapor rub on it daily It has definitely gotten lighter.

Good luck

Thank you. I have to go see a foot doc myself so we will see what they say. Thanks for the tip

No, been on it for 7 years with no problems.

I've been on Plaquenil for 15 odd years & no spots. If you're possibly on blood thinners, that could possibly be the cause?? I'm on blood thinners & have been told that, that can happen.
