I have had a lump in my earlobe for a few months now. At first it was nothing I figured cartlidge was built up and ignored it. It will get larger and become very painfull at times and stay for a week or so before it goes back down. It will get bad enough I can't lay on my side from the pain it causes. What could this be? It has me concerned now. I'm 19 and haven't ever had any other health issues like this.
