Clubbing of fingers?: You need to see a doctor and get this checked out. Although your description is not detailed enough, i would venture to guess that you are describing clubbing of the finger and toe nails. Log on to www.Nlm.Nih.Gov/.../ency/.../003282.Htm‎.

Vascular reaction: Is it you or an older relative? If it's you and you are otherwise young and healthy, it is probably a vascular reaction with vaso-constriction which shows up as a bluish discoloration of the extremities; especially the digits. In older compromised individuals, it may mean peripheral vascular disease.
