Migration is a common problem with body piercings. Migration happens when your piercing moves from its original place. It may seems impossible but keep in mind that a body piercing is essentially a wound that wants to be closed, so your body will find ways to try to heal it and close it. This may lead to the position of the hole changing. Typically, migration manifests itself as jewelry that shifts its position. The jewelry gets moved from its original placement to a nearby spot. One of the most extreme examples of migration is rejection, when the jewelry gets pushed out of the skin and the piercing hole closing. Once this happens you will essentially lose your piercing.
Sometimes, migration is minimal and temporary. For example, your piercing might move a little and after that sets nicely into the new place. If this happens, it is not so much of a concern, unless the original placement was the only suitable placement for your piercing. Other times, however, migration will be more substantial. It can be very annoying and even painful. A migrated piercing might ruin the aesthetics or cause further problems. Keep in mind that certain types of piercings, such as surface piercings, are more prone to migration than the others. It is very important to notice migration as soon as it starts developing. This is the only way to try to prevent the problem from getting worse. Common signs of migration include noticeable change in jewelry position, piercing hole appearing larger or smaller, redness around the piercing or pain. If you notice these signs, consult your piercer. It might be possible to change jewelry to stop migration from developing further.
