I had fluid building up in the upper cartilaginous portion of my ear. Over time if became about a centimeter and a half in diameter. I could squeeze the area and it would push the liquid within the skin as if it were tunneling toward my inner ear. I stuck an 18 gauge hypodermic needle in the lowest point using sterile technique to drain the fluid and upon its release it was a clear to yellow tint think viscous liquid, with the needle in place I messaged as much fluid out of the area as possible and alcohol and gauze bandage to the area. What could be the cause of this unexpected condition and should I have concern?
