My cartigle percing caused scar tiusse to form looks like a bubble . i got told tree tea oil will heal it. should i take out my earring to heal ?

Remove the ear ring: It sounds like you have developed a "keloid" type scar from the piercing. The scar tissue may resolve by removing the ear ring but you may need a small steroid injection into the site if it doesn't resolve with ear ring removal.

How old is piercing: You may be forming a type of thickened scar called a keloid....You should show your physician...Leaving the ring in place depends on how uncomfortable it is...
