What do you think about this permanent discoloration?

[character28]

Hi, I've been having this permanent discoloration and many other symptoms for more than two months. They were all triggered after overexercising. Doctors seem to focus on my other symptoms but not on the color of my fingernails. Before their colour was like that of normal, healthy people's fingernails. Also my lips, tongue, scars, scratches eg my face after shaving have this same discoloration. Please tell me all the causes of the discoloration. I'll attach more pics here. Thanks in advance.
