My ear piercing bleed and has a freaky lump?

2nd question for the day! Yay!
Anyway, so please listen to my story that I can't make short because I talk too much:
I got my left ear repierced because it had an infection back in May, and closed. So my blessed cousin, 21, offered to do it for me with a gun from Sally's Beauty Supply. She used all sterilized equipment, not problem there.
My stupid self went to Puerto Rico for a mission trip (oh this all happened last month, July 2009) and didn't even think about ever cleaning it. I maybe cleaned it once a week. DUMB ME.
Well Now, there is a freaky (literally it's awkward.) lump on the back of that ear lobe, right next to the hole. It's discolored and swells, with a tiny knot. I freaked out and I've been putting antibacteria cream on it for a while and that seemed to help. However, today I hit my ear on my boney boyfriends shoulder and that seriously ticked it off.
So I was told to wash it well and dry it. Nada.
Finally, I called my aunt, a doctor, and asked if she knew what I could do.
What I've done today:
Took out the earring for the second time.
Washed with Clair's Ear Cleanser
Washed with Witch Hazel
Dried
THEN….
it started to bleed. Not drastically, and it wasn't the lump, it was ear piercing in the back of my earlobe. My aunt told me it was probably because I had sterling silver in, cheap, and our family is prone to having issues with sterling silver.
What do you think the lump is? Should i be worried?

I think it's just a skin infection but I never do know anything when it comes to my body.

Thanks! Have a great day!
