A member asked:

One very tiny vertical super skinny red line is under my thumb nail... is this anything serious? will it go away on its own and how long will it take?

A doctor has provided 1 answer

Splinter hemorrhage: This is likely a splinter hemorrhage. This is very common after a minor trauma to the nail - you may not have even been initially aware of the inciting injury. It should go away in a few days. If it persists then I advise consulting a dermatologist.
