What Causes Ear Discharge?

I have this flood coming from the back of my ear and it's getting irritated and leaking more and more fluid

While I am sleeping the back of my ear seeps and the fluid dries into a crusty crud or it didn't leak an there is a look of flakey dry skin flacking off


There is alternating seeping and oozzing then dry flacking off as if it healed then seeping

This is on the back part of both ears on the lobe part away from my piecing
