Earring in old cartilage hole

Annie

So I had my cartilage pierced in high school. When I got my first "real job", I took it out... for the last 7 years. Out of curiosity, I tried putting an earring in last night, and it went right in without any problems! So I slept with the stud in, but today it hurts like helllll 🤬. What do I do to get this healed and in wearable condition again? Just suffer through the pain until my body gets used to it?
