28 yr old female. No significant medical history other thn endometriosis. I noticed a discoloration around the border of the lunula on my right big toe and 2nd toe. I have occasional numbness in my right toe. I also have this discoloration on my left big toe, but the right seems to be worse. All other toenails are normal, as well as fingernails. I'm guessing this is a peripheral vascular issue but wanted to get some opinions. Included is a pic of my right foot, a well as my right thumb so you can see a difference in the color. should I be concerned about this?
