First of all, don't call yourself a scar. This is the end of the cure. It seems that as soon as you consulted many doctors, you said all the basic treatments, and you became worried. But my personal opinion is surgical resection. You can go to a specialized hospital like Beijing Plastic Surgery Hospital for treatment.

Dr. Nie Lanjun, the Second Affiliated Hospital of Southern Medical University, solemnly reminded me that it is impossible to fully understand the condition because I can't see the patient face to face. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
