Well I noticed this since I was about 13, and forgot that I had this bump, and Recently I was thinking of getting my ear pierced and all but I realized this lump of some sort..

Since I pressed on it with my fingers and play with my earlobe I swallow, and it hurts?

Very weird, I'm actually scared to get this checked, I don't wan't to hear some sort of cancer or just something about my death will be caused by this!.

I've read some other posts on this forum about such,

Any more information about this?

and I'm only 15, I've also noticed the ages of 13 - 21 get these lumps often. :'(
