This question is rather ambiguous. According to the normal procedure, after the ear piercing, the ear piercing damages the skin tissue, the skin tissue has to heal and form a perforated hole, and the whole process usually takes 7-10 days to grow initially. It takes 1 month or more for the edema of the soft tissue under the skin to completely subside, which is normal. If there is infection, local redness, swelling, pain, and even purulent discharge, anti-infection treatment is needed, such as oral cephalosporin antibiotics or local cleaning and changing of medication, which may take 1-2 weeks to completely heal, so the healing time is relatively longer, and the specific time cannot be determined.
