All of my toes itch and look black. Does anyone know what could cause this?
Definitely see a doctor about this problem, Marlene. Have you been in cold weather? It sounds like it might be chilblains, which can itch and cause the toes to turn bluish black. It might also be a nail fungas, since those can itch and make the toes discolor. It's best to see a doctor, since this also might signal a nerve problem or neuropathy. Good luck, and keep us posted!
I only suggestion I can make is that you certainly get to a Doc, if your toeies are black.
Also do you live in a wintery climate? (Frostbite)
Have you been checked for Diabetes?
Good Luck to U
