Recently found a splotchy purple mark under big toe? (Photo)

I'm an 18 year old woman who recently found a splotchy purplish mark underneath my big toe, I work in hospitality and as a result my toe has suffered an ingrown toenail. I was wondering if the purple mark is a fungal infection or something more serious? I don't have any pain or other symptoms (other than a chest infection/bronchial infection that is separate), Fungal or melanoma?
