i think they are called splinter hemmorages. they sound fairly harmless. Or it could be some sort of fungal infection which is bad. I would just go to your doctor. Make an appointment, not an emergency one or anything, just to make sure your ok :)
Sometimes, you can hit your nails and it makes a bruise that looks like black lines.
I got the same thing,i think it has to do with not enough vitamins or some sh*t.
its has to with calcium in your body. drink your milk...not that fat free or 2% **** either.
