I see thin dark line from cuticle to tip of nail then nail splits, it gets sore. Must be a fungas, what should I do? I've had it for a year now. No stupid comments like cutting off my thumb!Thumb nail splits from cuticle to tip?
Is it on your hands or feet because my friend had the same prob on her big toes, and the doctor had to remove the whole toenail to fix the prob. It does sound like the same thing, maybe?
