Earrings can be thick or thin. Generally thick earrings are better for your ear as it keeps the hole open wide so you can fit thicker earrings into it wheras smaller earrings allow the hole to shrink to the size of the metal spoke in the earring. This is why when you get your ears pierced they to it with thick, good quality, gold-backed studs.
Usually just one will fit.
You don't get your ears pierced with earrings. You have them pierced by a needle and then the hole is filled with an earring. There are gold stud earrings which are less likely to cause an allergic reaction.
Clean the piercing area and gently press at the area of hole and put them in.
The bump inside of your earring hole is usually an indication that you have dirt, lint, debris or etc, inside of your hole. It should be painless which indicates that it is not infected. You just need to clean your earrings and ears with peroxide or alcohol and stick your earrings in your ear in the reverse, it should push the debris out.

I believe your ear hole closes, because when you don't wear earring's for awhile, the skin just grows together again. It's just like when you get a shot. The hole eventually grows together again. To avoid this, wear earrings continually. In the six month's, even wear earrings at night!
You could probably find stud earrings of any size, and reach a maximum when the stud could no longer hold the stone in the ear without tearing the hole open.
Your piercing is an open wound. If you don't keep something in it to keep it from healing then it will close up and you will have to get another piercing. Even after they've healed your skin is constantly making new skin cells, so if you leave your earrings out for a couple of months your skin will fill up the hole with new skin cells and it will close up again.
You your ears are newly-pierced and you don't want them, just take the earrings out.
