Possibly skin cancer?
Does this look like any type of skin cancer? I recently repainted my nails and when I took off the old polish these black dots and lines were there. It is on my toenail. It was not there a few months ago. 
@ReneeYork, thanks for reaching out. For your safety, we cannot provide medical diagnosis online. If you haven't already, I would encourage you to schedule an appointment with your dermatologist so they can have a look. I like to think it's always better to play it safe, and if ever in doubt get it checked out! I also thought this article from one of our advocates may be of interest to you https://skincancer.net/life-with-skin-cancer/bruise-or-nail-melanoma. Please let us know how you're doing. All my best, Julie (team member)
