Thank you. Those are much better.

This is melanonychia. There are a number of factors which militate toward a benign diagnosis.

I don't need to be concerned with this
Expert:  dermdoc19 replied 11 months ago.

1) The fact that two nails have lines 2) the border on both lines is sharp 3) the color looks even 4) the color is not too dark 5) I do not see Hutchinson's sign ( pigment spilling out to the skin around the nail

Expert:  dermdoc19 replied 11 months ago.

However, despite all these benign signs, my advice would be to consult with your dermatologist. They can examine the nail pigment with a special light called a dermatoscope. This helps to better look at the lines and be sure they are normal. Also, a dermatologist should follow the pigmented lines to be sure they do not change with time.

I do have lots of moles
Expert:  dermdoc19 replied 11 months ago.

Hopefully, a dermatologist is following you. I don't see a need to rush in Monday for an appointment but in the next month or so.
