How can i tell if i have finger clubbing?

See doctor: This is a physical finding on exam in which the fingers appear rounded like "clubs" however it is difficult to describe and takes experience to correctly recognize. If you think something looks wrong, best to ask your doctor about it.

Clubbing is: A bulbous appearance of the distal fingers. It's generally associated with lung disease. If you put the backs of your fingers together and don't see a space at the base of your nails, you might have clubbing.
