Hi, I have developed two black lines on the nail of my big toe. I currently have a nail infection that i discovered a few months ago and I'm treating it. I want to believe that its just splinter haemorrhages from filling and pulling at the nail (i used tiny scissor to lift part of the nail up). But I’m really freaking out its nail melanoma, keep reading about it and looking at pictures. There seems to be another black line at the edge, near the nail fold. Has anyone experienced this?
