I have noticed this blackness or tanning just down my nails..can you please tell me what is this..I have these on fingers of both hands but is more visible in right one. I have attached the photo, take a look
It was alsways there little bit but now it is more visible. Also i have googled about it and it shows
thyroid problem and other disease such as cancer and all..I'm terrified now. 6 month ago i have blood test and also thyroid test and my thyroid profile was normal and in ranges, but i have vit d and
b12 deficiency. And also i have dark knuckles.
Please take a look into the photo attached and tell me reason. I have severe health anxiety so I'm stressed right now.
