Small Bumps above my earlobe piercing HELP!?

On each of my earlobes I have a small bump above my piercing. The bumps are painless and don't ooze or anything, they are just there. I don't keloid when I scar. I did get them done by a gun at Claire's and used rubbing alcohol after the Claire's solution ran out. The bumps started showing about 5 months after I got them pierced. I really need to know what wrong with them. any advice would help
