i can't give a diagnosis without seeing the foot and performing diagnostic tests such as x-rays to determine why you have these discolorations.
if they are bothersome, get a second opinion from another podiatrist or dermatologist.
No its not on my toenails. But the flesh of my toe. right on the top of my big toes.
on the toe nail? where on the toe? if it is on the nail, that is dried blood. it takes a long time for them to grow out..
if you wear a shoe that has little height in the toebox, the toenails get bruised when you walk and bleed. the blood dries and has to grow outward with the nail. the nail grows 1 mm/month. it usually only happens to the big toes b/c they are the thickest and get rubbed more readily in these type of shoes. clogs can do this too...even though they are roomy in the toe box. the toes extend and brush up against the top of the shoe when you swing your feet during the walking gait cycle. this occurs more readily in clogs b/c the foot is trying to keep the shoes on.
