Black stuff on qtip from ear? is this a fungal infection? also lots of headaches, dizziness?

Ear: Not enough information to make an accurate assessment. Wax/debris from the ear can be various colors, mostly in the yellow-orange-brown family. If you were outdoors, and more specifically, in the dirt, you can have blackish color to your ear wax. You would need an evaluation with your PCP in person to take a look in your ear and take a complete history to make an accurate diagnosis.
