I took the jewelry out and can't get it back in, what do I do?

Well, first off, the jewelry should not be removed during the first stage of healing unless the jewelry is of the incorrect size or shape and even then only under the guidence of a piercer. Piercing heals by producing tissue starting at each piercing hole and then growing toward the center. The only thing keeping it in line is the piercing during the healing period.  Think of it like to teams tunneling through a mountian with piece of wire to guide them. If you take away the guide then often it is hard to match the jewelry with the other hole. 

Even after the piercing is healed, removing the jewelry for any extended period of time may cause the tissue in the center of the piercing to begin to shrink or reconnect regardless of how long you have had the piercing. Both piercing hole may look open but chances are there is tissue blocking the center of the piercing. The time it takes for a piercing to close depends on the person's health and the piercing location. It is best to remove the jewelry only to replace it. 

I do not charge to change or sterilize jewelry. Whenever you are nervous or unsure, see your piercer. Often times, even with well healed piercings it can be difficult to change jewelry, Especially if the jewelry is of a different type or size. Since it doesn't cost anything to have an expert do it, why take chances?

The biggest thing is that if you can't get the jewelry back in, don't panic or try to force the jewelry in because that may cause damage to the piercing. Some times even when the jewelry has been removed for a couple of days it can be reinserted using a taper pin.
