i have tiny brown dots under all my fingernails that i just saw today (i had nail polish on for a long time). more on my right hand nails, what is it?

Nail dots: These probably are from small broken blood vessels under your nails. It may be no big deal, but since it is on multiple fingers of both hands, could represent something more serious and I'd get it checked out by a doctor. Some simple blood tests would be a good start.

Fingernail Facts: Commonly, when fingernails are painted for prolonged periods they can become infected with a fungus due to trapped moisture and poor air circulation. If the discoloration doesn't resolve after unpainted nails for 1-2 weeks, a culture or biopsy of the nail may be helpful to determine the issue. Staining is also common in some cases, and may resolve with buffing the nail surface.
