Dark spot on toenail

I have had this big dark brown almost black spot on my big toenail. I tried treating it with tea tree oil for a week and there is no change. I’m scared it could be melanoma? It’s only under a nail and not growing out, nail is a bit yellow but not much, spot takes about 1/4 of a nail and doesn’t really have a shape. I’m a teen and really don’t want to go to my parents so that is why I am asking and also don’t want to go to the doctor if not really necessary.

    Hello and thank you for your question. Often times black areas under the nails are bruising and dried blood from prior injury. Melanoma typically presents as a line or streak that runs the entire length of the nail starting from the base of the nail. If you truly suspect a melanoma a biopsy of the nail bed would need to be done to rule this out. If you can send a picture that would better help me advise you.
