I noticed this week I had stained tip of both thumbnails. Took polish off tonight and saw this. There are some slight tinges on other nails but worse in this.

I feel panicked for the first time in a few weeks. I've read about how yellow nails are symptoms of some cancers.

I did have a curry last Friday but have and always do wear nail polish so not sure it would stain through? I'm so scared right nw.
