Does anyone know what could cause these brown lines at the cuticle and on the actual hand? Person has athletes foot, jock itch, and Versicolor. Also suffers from severe abdominal cramping and bloating frequently. based on my research online, the only instances I can find a brown lines on the hands and fingernails occurred in people who have parasitic infections. After contact, I am now getting the brown lines in (not under) my fingernails without injury. Also peeling between the fingers.
