For the most part, piercings have pretty few drawbacks and serve as a fun way to express oneself and experiment with body modification. That being said, migration and rejection are the exception and can be an issue that's both frustrating and frightening for the person experiencing it. What's more, the two words are often mistaken for one another—which doesn't help matters—so we're here to help with that. Below, find a deep-dive on migration and rejection that'll clear things up once and for all.
Rejection vs. migration
Put simply: Rejection is a cause and happens because of migration. It occurs when you place a foreign object in your body (i.e. a piercing) and for one reason or another, your body considers the foreign object to be a threat to your health. Thus, in order to protect itself, your body slowly fights the object by pushing it and healing the skin behind it, which eventually forces the piercing back out through the skin.
On the flip side, migration is a symptom. When your piercing is migrating, it's attempting to move from its original spot to a new one, and in some cases, can result in a full-blown rejection. It's definitely something to look out for because if the jewelry is not removed in a timely manner, it can get completely rejected and result in scarring from the puncture and put you at risk for infection.
Piercings most likely to reject and migrate
Piercings that only break through a small amount of surface skin—aptly named surface piercings—are most at risk for rejection and migration. This is because the less skin there is to help keep the piercing secure, the higher the chances are that your body will find a way to push it out. Of course, this totally depends on the person, as some people are simply more prone to rejection than others.
The most common surface piercings are belly button and brow piercings. However, the piercings most likely to reject are those that reside closer to the skin's surface, such as sternum, nape, and madison piercings. A skilled and experienced piercer will know how to pierce through enough flesh for a secure hold without causing tissue or nerve damage, albeit even a perfectly placed piercing can still reject if your body doesn't want it there.
How to tell if your piercing is migrating
Because migration is such a slow process that can take weeks or even months to play out, it can be tricky to tell for sure if your piercing is actually changing. A few symptoms to look out for are constant soreness and sensitivity, the skin over the piercing getting thin enough to see the jewelry through it, the jewelry hanging more loosely than it used to, and the hole around the piercing appearing larger. If you experience any of these, you should go see a doctor, ASAP, to keep it from getting worse.
What to do if you're piercing is migrating
Unfortunately, once a piercing has begun to migrate, there isn't too much you can do to stop it. It's kind of like a relationship gone bad. What you can do, however, is prevent it from getting worse. The best thing to do is see a doctor and have it removed, as this will at least allow what's left of your piercing hole to heal completely.
Is re-piercing safe?
Some fear that if their body rejected one piercing, it might reject all of them, which is not a crazy theory but also not necessarily the case. If you do want to go for it again, opt for a different kind of jewelry material, like niobium or titanium, instead of stainless steel. Choosing a different location is a good move, too. Above all, be sure that a professional does your piercing so you can trust it'll be done properly and make sure to keep a close eye on it afterward.
