Healing Times Are Different Depending on the Piercing
It's important to know that it's best to wait to change the jewelry until the piercing is completely healed, which can take up to six months — sometimes even more. Earlobes heal relatively quickly in comparison to cartridge piercings, due to the type of skin the jewelry resides in. After several months, my earlobe piercings were completely healed; I was able to take them out for days at a time or switch jewelry without a problem.
In contrast, with my nose piercing, I waited a strict six months before taking it out to change the jewelry, and still had problems with sensitivity. If I left my piercing out for a mere two hours, I would have to nearly repierce my nose to get the stud back through the hole.
