Finger clubbing

Finger clubbing is a condition where the nails become curved or rounded, the fingertips enlarge, and the angle between the nail and the nail bed increases. This is due to soft tissue swelling of the fingers. This can be a sign of multiple health conditions, such as liver cirrhosis, lung cancer and bacterial endocarditis.
