I went to see a dermatologist yesterday as I've had a think black line come up on my ring finger nail. They have booked me in to have a biopsy taken from it next week. Having read things online about subgenal melanoma I am now getting myself very worked up about it. I suffer with anxiety and depression and I cant get the bad thoughts out of my head worrying that it is melanoma. Just looking for anyone that has had similar issues or knows more about it please.
