About 6 months ago after gardening I noticed that my nail on my forefinger appears to be cut in little rings. I thought this would go but now after several months in spite of cutting my nails these cut rings are still there. What could this be?

I can't actually picture what is wrong with your nail. Can you take a picture of it and post it. We don't diagnose on AMHD but now I am curious, so could possibly help.
