Hi, I've had three different dermatologists treat a stubborn keloid scar on my chest over 10 years. I've had multiple rounds of steriod injections into my keloid scar and all that has happened is that it's trippled in size and is still painful and itchy. I've read steriod tapes with injections might work but my current dermatologist refuses to prescribe it. What other options are there? Should I see a plastic surgeon instead, are they more experienced at treating scars?
