There are different types of tissue in different parts of your ear, so how long it takes to heal depends on your body and the place you’ve pierced. Earlobes usually take 6-8 weeks. If you pierce the cartilage on the side of your ear, it can take 4 months to a year. Ask your piercing professional for an estimate.
Just so, can I bring my own jewelry piercing?
There is no harm in bringing your own earrings provided they are light in weight and not too heavy for you to carry as it pains after the piercing is done . The pain may be prolonged for weeks so wearing heavy earings will create discomfort and will give you more pain.
