Horrible Scar After Ear Otoplasty?

i have a very bad raised super white scar on the top of my left ear, its very hard i feel like its a cartlige but im not sure, it has been 3 and a half months since my procedure. i have started using silicone sheeting ive been using it for about 5 days, nothing has not changed. is it normal for someone to have this? do u think its a cartlige if its hard and white? because when i saw another surgeon for this he said that maybe its a suture but then he was like no i dont think so. please help!
