So it’s like it popped up out of nowhere these faint vertical lines on both my big toenails and I think it’s starting on the nail of my thumb as well I’m going to docs for other reasons on Monday will ask him about it don’t know how long it will take to get an answer anyways thought I’d ask if anyone came across or had similar experiences 😊 plz excuse my toe pic lol

That’s my thumb I think it’s starting on as well
