Went to different dermatologist, they all identified it as kelloids or kelloidus. It is mainly concentrated on middle chest, and other single kelloids are on back and shoulder. One of the doctor suggested me nitrox jet spray treatment or injection coould heal it, but couldnt guarantee that it would not reappear in future. Is it true? Is rhisbincurable? If not then, with due respect can i have some curable medical assistance please.
