It could be a bite. Odd place for an injury and less she jumped up and hit something pinpoint like?
The "green spot"! Ugh! It reminds my of the black spot on Jack of the Pirates of the Caribbean.
The light green spots can, of course, be a number of things. Over the years, dealing with stressed and sick frogs, I've noticed two things, first, that they often start showing up with stress or illness. In retf' you can see a light green spot right on the top of their heads between their eyes when they stress. Several spots are generally indicative of a bacterial infection.
I would apply original neosporin to the black spot and the green spot. Hold off on the other treatments just yet. Do not use the kind with pain reliever, it's toxic to frogs. Use a Qtip and just gently swirl it onto the areas.
How was her energy today? Is she moving around?
