There is a bag at the root of my earlobe. I feel round, painful and hard when I pinch it. As shown in the picture, what is this situation?

Hello, this is external auditory canal furuncle, localized purulent inflammation of external auditory canal skin. Digging the ear or unclean liquid often flows into the ear, causing severe pain in the early stage. When you chew with your mouth open, the pain intensifies and causes headaches. Earache can be relieved after furuncle and ulcer. It is suggested to control infection and get rid of bad habits. If you can't get down after a while, you can also take it out surgically.
