I don’t have recommendations relating to keloid scars. But you might get better results with a dermatologist for the more superficial ones. My kid’s scars are completely gone - and they were all over, not just the arms.
As for intrusive questions, you’ll get them. It would be malpractice for a doctor not to ask. I mean, imagine if they were the last provider to see her before she went out and committed suicide. That’s a lawsuit asking to happen. How you deal with the questions is a different matter. We were just matter of fact and shared that we had good mental health support.
