Dear Gary,
Thank you for sharing your experiences.
I am not a Dr. or anything like that but I have heard that this does have to do often with heart disease the purple discoloration of fingernails.... I knew a women once in Germany where that was the case also
Dear Ben,
This may suggest heart or pulmonary disease and should be evaluated by your internist. It is important to know if you are getting adequate oxygen in your blood stream. This may aso be due to Raynauds or abnormal constriction of your blood vessels.
Each time I get a heart checkup, my cardiologist first examines my fingernails for color and presses lightly on them to see how fast the color returns. Might be something to it.
