Hi I Am A Slim And Athletic 55 Year Old

Hi I am a slim and athletic 55 year old woman. Lately I have noticed the moons in my big toenails , which have been absent for years, are very much back. The moon is quite light with a pinkish, sometimes bluish halo above it. the rest of these two toenails usually have a blush of pink, dark pink or often bluish color. Also, though maybe inconsequential, the moons are not properly shaped half moons, rather each leans toward the little toe. My fingernails are fine.
