Hello Everyone

I had black dot on my feet that disapeared and reapeared (smaller size) on my right index finger after several week it also disapread and reapeard on the same finger but at different place.

Can anyone tell me what can it be ? 

I have shown it to several doctors but thay could not find out.

It looks like a wart, they are highly contagious, so if you were touching your foot that may be why you got it on your fingers. They often disappear, my grandmother knew someone who would "buy" your warts! Probably a real con as they knew they would go of their own accord.

Thank you for your answer.

Is this think  deadly  ?

I don't think it is deadly! The little black dots are probably tiny spots of blood on the wart.
