Toenail turning blue?
I didn't get hurt, my big toe just randomly turned blue on the bottom of the toe.
Bad circulation? Or perhaps it's just a tissue bruise, could have happened anywhere, even in your sleep! Or a small bump that didn't register in your mind at the time could have done it :)
Go to the docter
maybe you got hurt and you didnt know it ... idk see a doctor
go to a doctor doesnt sound healthy???? :-/
Mine turn purple. My feet are always ice cold too and extremely sweaty. I think it's bad circulation though.
