Toenail cancer or bruise? Am I crazy!!

LyssAnn95

Hi everyone!! I am a 24 yr old healthy female and I have had this small black spot under my big toenail for approx 6 months...I think. I don’t really know how long because I paint my nails. But it started out small and in the middle right side of my nail touching the skin. It was just a black spot. Now today I took off my nail-polish and half of my toenail is black. I did drop a heavy dryer on my toe a couple days ago and it only hurt for an hour or so then it stopped so I don’t think it would have caused this to occur? I think back to when I had the random black dot under my nail and it’s been a while since I last took my nail polish off so I can’t even say how long it’s been like this. It doesn’t hurt at all though! If it was a hematoma wouldn’t it be tender if I pressed on it? Maybe it’s toenail fungus? I work at a dog kennel and get water in my boots pretty often. But I’m scared to death it’s cancer. My mom passed away from cancer three years ago so it immediately comes to mind because it scares me so much. I made an appointment for the dermatologist for October 10th but I need some reassurance lol or I will worry myself to death until then!
