Blotch and black lines on nail

Patient

Q: Hi

Over the past few months I have noticed a small vertical black line on both my thumb nails.
On my right thumb a pearly looking blotch (3mm x 4mm approx) is also developing.

I consider myself healthy, regually exercise and eat a varied diet.

I do however bite my nails a little if this makes a difference.

Can you please help?

Thanks

Tim
