I had the same problem, I ended up removing the earring altogether, (about 3years ago!) but I can still feel where it was and every now and then it swells up and is sore. I also have a lump all the time which I assumed was just the edge of the cartledge/scarring
with my other ear piercings I used antiseptic wipes and turned the earring at least once a day.
Best way to let it heal is keep it clean and leave it alone. I you do take it out you might not get anything back in at a later date without re-piercing, which may not be possible in the same place
