What Causes Recurring Bump Under Ear?

I have had a squishy bumb above my ear diagnal from my temple the first time I thought it was a mosquito bite and left it alone this time I thought it could possibly be a under the skin type pimple so I squeezed it again and again nothing happened so I got a sterile needle to pierce it only because it was tender and painful to the touch . After I pierced it with a needle and squeezed it again the most disgusting thick green pus came out followed by a lite flow of blood I can not find anything on line that matches it with a picture and description
