Thanks chitchatnine for the comment
I will seek another opinion. and i hope everything will be allright with u..
Hi, I am not a doctor but had similar and for me it turned out to be black and blue marks under the nail bed from trauma (ill fitting shoes, etc.). I have history of Melanoma so they took it VERY seriously and said same thing .. since bilateral to watch .. and they grew up and out within 6 mos for me. Do keep in touch with your Dr and/or have a 2nd opinion if not feeling comfortable with her DX.
