I have a small pimple sized keloid on the front of my earlobe. From a piercing that got infected about 7 years ago. It stop growing after I took the piercing out. I'm mixed skin type. Should I try cyrotherapy or steroid injection shots from a Dermatologist? I don't know what to do but I'm tired of this keloid scar and want it gone. Please help me and tell me what I should do.
