Ive had a lump the width of a quarter behind my left ear since about 12 years old. I am now 33. It doesn t hurt. It only swelled up once, about a year ago and had liquidy pus in it. After it burst, it went back to its original size and texture, hard. Today, i noticed a small opening on it. When I squeezed it, a brown gooey consistency oozed out like a worm, after a while, nothing else came out and it remained hard as it had always. It is not painful though. My grandmother had lumps on her neckand ear area but it was determined as just lumps? I am not sure if this has anything to dp with it?
