My 6 month old son has a red line that appeared 3/4 of the way around his ankle 4 weeks ago. it s not raised, bruised or sore and it didn t come from pants or socks being too tight. it has not changed in color, nor has it gone away. the pediatrician says it has something to do with his skin pigmentation and that is will eventually disappear and I shouldn t be worried. today though a thicker, darker line appeared 3/4 of the way around the same ankle out of nowhere. could these marks be a sign of a disease or sickness?
