Dear, ,
I have a black line on my right thumb of foot nail. I just noticed it a few days ago. After reading some stuff on Internet, I am worried about it. I have a brown skin and my age if 32.
Please note that, last month I gone throw a medical check up for my new job and doctor told me Internal fatness ratio probably in blood is higher than normal.
I am seeking for some professional answer on this.
Regards,
