I Have a Bump in my Ear !?!?

I got my ears pierced at a 14 gauge about a month ago and I changed the plugs in my ear. I could not see the hole so I asked my mom help to put it in. BUT, before she put it in she held my earlobe with a lot of pressure. My ear has been hurting since, Today I took out the plug to clean my ear with salt water and noticed a bump. Is it an infection or just a temporary bump?
