I first noticed my fingernail beds were about half or more purple around six years ago, which was when I found out I had anxiety disorder. I read that it can indicate poor circulation, but about two years ago I had a blood and urine test, chest X-ray, and several EKGs, and everything came back normal.
I have no history of medical problems. There is also a history of great health in both sides of my family. The only thing I've been diagnosed with in the past other than anxiety is ADHD and possibly a form of Aspergers.
I asked someone else on here and they suspected Hypoglycemia.
Do you have any idea what this may be? Lately I have some small pale areas near the tips.
