Faint black line on my nail!!

Hello, I'm 17 and over the past few months I've had a faint black nail on my right thumb nail. I went to get it checked and she told me I have a vitamin deficiency. It's not in the root of my skin it's just on my nail. But everytime my nail grows the line grows with it. Since yesterday under my nail has been sore and my thumb has been too I was just wondering if it's serious I used to bite my nails a lot too.

  • Hi Em134,

    It sounds like you may now have an infection in the nail bed which may, or may not, be linked to the line in the nail. I suggest you go back to your GP to be checked out. It's very unlikely it's subungal melanoma as it is rare and the line would be in the nail bed. But it does need getting sorted out if it's infected.
