I have three spots under toenail. 1st dark and roundish. 2nd lighter in color sort of bar shaped both smaller then a number 2 pencil point. 3rd is a reddish smear more then a spot. All three are on the same side of the nail. I have not dropped anything on my toe in recent memory but I did stub my toe a few weeks before I notic d the spots and the nail was sore to push on.. It's not sore now. Also the three marks did not all appear at that same time. They came several weeks apart. Thanks for your help
